Design Challenges

The team aimed to implement numerous geometry optimizations to reduce drag but initially faced challenges in identifying the most aerodynamically effective solutions. To address this, they utilized SimScale’s CFD tools to simulate changes in drag force resulting from modifications to various parts of their car. Their CAD models were created in Onshape, and thanks to SimScale’s direct integration with Onshape, the team was able to import their car bodies seamlessly—greatly improving workflow efficiency compared to other CAE software.

In addition to CFD, the team also leveraged SimScale’s FEA suite to optimize components such as the wheels and the wing support structure, ensuring these parts were both lightweight and structurally sound.

The integration of several CAE tools within a single streamlined user interface makes SimScale, compared to other options, very easy and convenient to use.

How SimScale Simulations Led to Success

To set up their CFD simulations, the team imported their car geometry from Onshape into SimScale. They created an external flow volume, applied boundary conditions including a pressure outlet and moving wall to simulate ground and wheel motion, and selected an incompressible steady-state analysis using the k-omega SST turbulence model. A region refinement was added around the car to improve mesh resolution, and force/moment controls were used to track aerodynamic performance.

For FEA simulations, the team imported their wheel geometry, applied appropriate boundary conditions (a 60N vertical load and fixed support), and increased mesh quality to improve accuracy. These simulations were key to optimizing weight and structural integrity.

One major challenge was fine-tuning the car’s body design for aerodynamic efficiency. After researching natural streamlined shapes, the team experimented with a concave front-end profile inspired by penguins, which research showed had a lower drag coefficient than traditional teardrop shapes. Simulations confirmed their hypothesis: the concave body produced less drag (0.354N vs. 0.362N), leading the team to adopt this optimized design. The pressure visualization tools in SimScale were especially helpful in guiding this decision

Using just a few core hours, the team achieved an excellent CFD convergence with acceptable range of residual values showing an improvement over the method used in the previous season despite lower computational cost. Over the course of the project, they ran 165 simulations across both CFD and FEA. The standard meshing algorithm with a fineness level of 5 proved most effective, with region refinements providing sufficient accuracy.

SimScale proved to be an invaluable tool throughout our development process, offering both efficiency and ease of use. We’re excited to continue this partnership as we head into the World Finals.

This growth has also been fueled by an equally rapid expansion of model capabilities. The first steps toward multi-modality came quickly and introduced the same text-to-output inference to other content types. We already almost take for granted the ability to generate high-quality images, video, and source code through such tools.

Can AI Generate Engineering Output?

Mechanical engineering teams have adopted these tools as well to accelerate all sorts of work processes. For example, to analyze and summarize RFQs faster or to search faster for technical information. But these use cases are mostly adjacent to the core engineering work and mechanical design. So why is it that we can ask AI to generate very useful text, images, video, and code but not a useful engineering design?

Let’s consider how these types of AI models are trained. Generative AI models have been trained on trillions of tokens, primarily from the internet. Transformer models on huge datasets of public text/code and diffusion models on equally large datasets of text-image pairs. Not only is this training data available in vast quantities, but the data formats are also very straightforward to read and use for model training.

Things look rather different in the engineering realm, the most obvious challenge being that, unlike text or source code, there is little to no public product design engineering data available. Then there is also the question of data quality, in the sense of whether or not a given design is fit-for-purpose, meeting the requirements that it was designed for. Added to that is the fact that the most widely used data formats storing mechanical design information are proprietary, requiring commercial licenses even to read it, let alone manipulate it. In summary, the idea of obtaining and processing millions of engineering designs to train a generative model still looks like a very challenging ask today, but technical progress in this field is happening fast.

Does That Mean That Core Engineering Work Will Remain AI-Free for Now?

Absolutely not. In due course, novel AI approaches might rise to the challenge of handling big chunks of typically manual engineering workflows, possibly including the transformation of a text prompt into a meaningful design, but it is going to take time to get there.

Meanwhile, there are AI engineering workflows that are easier to attain while still very helpful. We can get a long way by using AI to speed up the cycle time for a single design iteration to such an extent that it appears to be instantaneous. We will do this by accelerating all of the steps in the workflow, including CAD generation, model preprocessing and setup, simulation workflows, and the analysis of results.

Once we have all that proven out, an AI agent can then drive the (accelerated) machine, taking design decisions along the way and looping around to discover optimal solutions.

Replacing a human-in-the-loop with a machine-in-the-loop in this way has the advantage of leaving the workflow and toolchain fundamentally unchanged, with the AI system ‘driving’ the tools in the same way that a human does. This means the human can easily understand what is being done and intervene at any point. Most importantly, the human can provide input to direct the AI, for example, where a design needs to balance competing objectives – decisions that require careful consideration and mutual understanding.

Not Just a Case of “Prompt Engineering”

Let’s dig into how we deploy AI to accelerate and augment engineering workflows. Let’s start by looking at how these processes work today. They tend to be centered around the manual engineering work where humans make decisions to advance the iterative design by designing and evaluating the design’s performance, depicted in green below. The CAD system involved can be conceptualized as a computational process going from parameterization to geometry (yellow) and the CAE system going from the simulation setup to the results (blue). 

This is a very simplified conceptual view of the engineering process, but helpful as it differentiates between the unstructured, human workflows in the middle and the purely computational ones left and right. All three can be automated already, to search through a prescribed design space for example. But this automation is very much rate-limited when using so-called traditional physics solvers to evaluate each design. What’s more is that AI can transform this process into something not only automatic, but autonomous.

Introducing Physics AI & Engineering AI

Let’s tackle that first bottleneck of simulation run time (the right-hand block in the diagram above). Depending on the physics and fidelity needed, a computing time of hours to days is not unusual. A growing set of AI methodologies to speed up this solve process is available, from deep learning surrogate models that replace full physics solvers to tools that speed up those ‘traditional’ solvers. Given the availability of a suitable, pre-trained, method, you can reduce the solve time almost to zero. We call these ‘Physics AI’ methods to indicate that, at the core, it’s about predicting physics with AI, and with the big benefit of being able to do that very fast. 

The second, more dispersed bottleneck visible in the process is the human interaction needed to go from a given design to a well defined simulation setup, then to consider the results of that simulation, and lastly to determine which point in the design space to look at next (the middle block in the diagram). These are all steps where an AI agent can assist, facilitate, accelerate, as well as act autonomously – performing complete workflows by operating on the existing tool stack just as a human would. As such, it is performing a series of discrete and logical steps that can be justified or even debated, as you might with a colleague. Since this agent is performing the core engineering work for you, we refer to it as ‘Engineering AI’.

Lastly, let’s turn our attention to the left-hand block – the CAD definition of a design. Once a model has been created and parameterized, generating a new variant based on a new set of parameters is already near-instantaneous. What is very much slower, though, is the process of creating that CAD model in the first place.

There are several exciting technologies emerging in the CAD space that could make the process of CAD generation far faster and more robust. Latent space parameterization, implicit representations, and cloud-native BREP are just three such technologies that could enable vastly faster design iterations, and we are actively working on integrating them into SimScale.

We Are Placing AI Tools in the Hands of Every Engineer

Thanks to its cloud-native architecture with built-in AI infrastructure, SimScale is uniquely able to provide AI features to help you navigate engineering workflows and accelerate performance predictions by leveraging your simulation data in the cloud. As we have explored so far in this blog, unlocking value from AI means touching almost every aspect of the simulation workflow. It requires a deep and immediate connection to models and data which is only practical to do in a cloud-native stack.

Engineering AI and Physics AI are built into SimScale in such a way that it can become second nature to use these tools to supercharge your productivity. SimScale users do not need to deal with any of the typical headaches experienced when attempting to deploy AI tools such as data cleaning/organizing/relocation, model versioning and management, or provisioning of suitable GPU resources for model training and execution. All of these are taken care of by the vertically integrated tool stack and intuitive user experience.

At NVIDIA GTC 25, we announced that we are making it even easier and faster to adopt Physics AI for certain applications by building a set of pre-trained foundation models. The unique aspect of these models is that they are pre-trained on a broad set of designs, providing users with a Physics AI model that they can use out-of-the-box or that they can augment with a small amount of their own proprietary training data. To learn more about foundation models in SimScale, check out this blog.

Unlock AI Value by Selecting an Impactful Application to Start With

Once you have test-driven the capability, the next step is to test-drive the value unlock. Each engineering team we work with has unique legacy data stored, sometimes from decades of engineering work. We frequently see teams expecting to start there, trying to find value in it. The reality is that finding and processing legacy data can be an immensely difficult task, and one that may take a very long time to yield results, even if useful data exists.

We recommend a different approach: Select an engineering process in your organization that – if collapsed to seconds – would create hard value for your organization (revenue or costs) and try tackling that with an AI-powered workflow. 

Remember: The best time to start leveraging AI systems in your engineering team was yesterday. The second best is today – give us a ring!

How SimScale Simulations Led to Success

The team began setting up the simulation by importing half of the full model to optimize meshing speed and calculation efficiency. A flow body was then created with dimensions closely matching those of the track. By utilizing a combination of cutting planes, particle traces, and force coefficient graphs, the team effectively refined key components of the car, including the end pods and front wing.

Throughout the project, challenges were minimal; however, a significant setback occurred due to a meshing issue. Upon investigation, the team identified the problem as a modeling error, which was quickly resolved using a few additional modeling commands, allowing the development process to continue smoothly.

The simulations performed exceptionally well, with each run completing meshing and computations within just a few minutes. The initial simulations took approximately 25 minutes to run, utilizing around 20 core hours. Overall, the software operated smoothly, enabling quick adjustments to both the model and the simulation settings and streamlining the development process.

With engineering simulation now a critical part of motor testing, engineers can analyze thermal behavior, predict electromagnetic performance, and identify design flaws before physical testing even begins. In this guide, we will explore how to test an electric motor, its advantages, and the different test methods that guarantee safety and efficiency.

Introduction to Electric Motor Testing

Electric motor testing is the process of evaluating the performance, reliability, and safety of an electric motor before manufacturing begins. It includes testing factors like electrical parameters, mechanical integrity, and thermal stability to ensure the motor runs well over the long haul.

Electric motor-driven systems consume around 46% of the world’s produced electricity. When a motor underperforms, it directly hits efficiency, safety, and operational costs.

We’re not talking about the price tag of just the motor itself here—that’s a drop in the bucket compared to what it costs to operate and maintain it. To truly understand the expense of an electric motor, you have to look at the Total Cost of Ownership (COO), which is broken down like this:

COO = Purchase Price + Cost of running + Cost of not running

The cost of operating the motor—think energy consumption and routine maintenance—often makes up about 70–95% of the total expense over its service life, which could span 20 years or more.

Before building a physical prototype, a simulation-driven electric motor design lets you optimize performance parameters and spot potential issues. Running virtual tests on your motor helps you see into the future—how your electric motor will perform five years down the line after continuous load variations and environmental stresses.

Types of Electric Motor Tests

Electric motors endure a wide range of stresses, so they must be tested mechanically, electrically, and thermally to ensure optimal performance and longevity.

Electrical and Electromagnetic Testing

Electric and electromagnetic testing ensures that the motor’s electrical parameters align with design specs and that the electromagnetic interactions within the motor are optimized for efficiency and minimal losses.

Proper analysis can prevent potential issues like electromagnetic interference, unexpected power loss, or thermal overheating, which could ultimately lead to motor failure or sub-optimal performance.

Engineers should pay close attention to the following parameters when running electrical and electromagnetic tests:

• Winding resistance and inductance: Evaluate copper losses and magnetic behavior
• Insulation resistance: Ensure no short circuits develop between the windings and motor frame
• Magnetic flux density: Measure the strength of the magnetic field within the motor, impacting torque and efficiency
• Electromagnetic field distribution: Identify potential hotspots and irregularities in magnetic field lines

SimScale is a cloud-based simulation platform that allows engineers to analyze and optimize electric motor designs through various electromagnetic simulation tools, including magnetostatics, time-harmonic magnetics (AC magnetics), and electrostatics.

These tools enable the visualization and analysis of key parameters like magnetic fields, current densities, and electric charges, allowing for parallel simulations and design iterations to improve motor efficiency and performance before physical prototyping.

Mechanical Testing

Mechanical testing identifies how the motor’s components behave under mechanical loads, including rotational forces and vibrations. It’s usually done using Finite Element Analysis (FEA), a powerful simulation tool for evaluating the physical properties of an electric motor’s components.

A well-designed mechanical structure ensures the motor runs smoothly, minimizes noise and wear, and maintains performance over its lifespan.

Engineers need to analyze the following mechanical parameters to ensure the motor’s structural reliability:

• Bearing load and life expectancy: Assess the distribution of forces on bearings to avoid premature wear
• Thermal expansion and stress: Analyze how temperature changes affect material properties and structural integrity
• Fatigue analysis: Study how repeated loads impact motor components over time to predict potential failures
• Torque and rotational forces: Measure forces exerted on components to ensure efficient transfer of power
• Mechanical resonance: Identify natural frequencies that could lead to destructive vibrations under certain loads

SimScale provides cloud-based mechanical simulation tools for engineers to analyze structural behavior in electric motor components. Its capabilities include static stress and deformation analysis, dynamic response to shock or vibrations, and modal analysis to identify natural frequencies.

Additionally, it allows thermomechanical simulations to assess how temperature changes impact motor structures, offering a comprehensive approach to optimizing designs before prototyping.

Thermal Testing

Heat is a critical factor in electric motor performance and, if not properly managed, can lead to component degradation, reduced efficiency, and, eventually, motor failure.

Motors must effectively dissipate heat to maintain optimal performance, as excessive temperatures can damage windings, bearings, and insulation. Thermal testing is essential in assessing how well a motor handles heat over time.

For comprehensive thermal analysis, engineers should evaluate:

• Heat dissipation efficiency: Assess how effectively the motor can release heat into its surroundings
• Temperature rise in windings: Monitor winding temperature to prevent insulation breakdown and motor burnout
• Thermal conductivity of materials: Evaluate how different materials conduct heat within motor components
• Ambient temperature and cooling methods: Understand the effect of surrounding temperature and cooling techniques like convection, conduction, and radiation
• Thermal gradients: Identify temperature differences across different sections of the motor that could lead to mechanical stress
• Hot spots and thermal resistance: Detect areas of high thermal concentration and resistance paths to optimize heat flow

SimScale’s platform offers comprehensive simulation tools for thermal management, allowing engineers to analyze heat transfer through conduction in solids, convection in fluids, and radiative heat transfer.

The platform can simulate various scenarios, including forced and natural convection, cooling efficiency, and the effect of thermal loads on mechanical structures.

Performance Testing

Performance testing evaluates an electric motor’s operational characteristics to ensure it meets its designed capabilities. The goal is to simulate real-world conditions and validate that the motor performs optimally throughout its expected load range and applications.

The following key performance tests reveal how well a motor can maintain torque, speed, and efficiency across its working range, helping engineers optimize its design for consistent and reliable performance.

• Load Testing: This test measures the motor’s response under various load conditions to understand its behavior under full, half, or overload scenarios. It identifies any drop in performance, helping engineers verify that the motor can handle its rated load without overheating or excessive vibration.
• Torque Measurement: This test assesses the torque the motor produces at different operating speeds and load levels. This is crucial for understanding how well the motor can drive its intended application, particularly in dynamic systems where torque variations can significantly impact performance.
• Speed vs. Load Characteristics: This test evaluates the motor’s ability to maintain consistent speed as the load changes. In real-world applications, motors may experience fluctuating loads, so understanding how speed varies with load is vital for ensuring stable performance.
• Efficiency Testing: This test analyzes the motor’s ability to convert electrical energy into mechanical output. Here, the focus is on parameters like power factor, losses (electrical, mechanical, and thermal), and overall efficiency to maximize performance and minimize energy costs over the motor’s lifecycle.

Electric Motor Testing Standards

Electric motor testing is governed by several key standards to ensure safety, reliability, and compliance across various applications. These standards are developed by organizations such as:

• IEEE (Institute of Electrical and Electronics Engineers)
• NEMA (National Electrical Manufacturers Association)
• IEC (International Electrotechnical Commission)
• BSI (British Standards Institution)
• JISC (Japanese Industrial Standards Committee)

Each organization sets guidelines for testing procedures, performance benchmarks, and safety requirements.

Engineers must understand and follow the appropriate standards as they vary based on motor type, intended application, and geographical region. For instance, testing requirements for motors used in explosive environments (ATEX) differ significantly from those for standard industrial applications.

Likewise, motors destined for the North American market may need to comply with NEMA standards, while those aimed at a global market may need to align with IEC regulations.
