The Static<\/strong> analysis type allows time-invariant calculation of displacements, stresses, and strains in one or multiple solid bodies. The results are a consequence of the applied constraints and loads, for example, bearings, gravity, forces, etc. In SimScale, Code Aster<\/a> solver is used for performing static analysis.<\/p>\n\n\n\n

The results enable you to evaluate whether your component is deformed in an undesired manner or if a critical stress state occurs in your geometry. Additionally, you can also iterate the design based on the simulation results and run as many simulations in parallel as you want. You can find an overview of the fields of application at the bottom of this page.<\/p>\n\n\n

This document will describe the different simulation settings that need to be defined to run the simulation.<\/p>\n\n\n\n

Global Settings<\/h2>\n\n\n\n

The global settings can be accessed by clicking on the simulation name, in this case, ‘Static’<\/strong> in the simulation tree. Here you can define if the analysis will be linear or nonlinear. For more information, check the global settings<\/a> page.<\/p>\n\n\n\n

Geometry<\/h2>\n\n\n\n

The geometry<\/em> tab contains the CAD model used for the simulation. Details of CAD handling are described in the pre-processing<\/a> section. For more information on the CAD upload process and the subsequent steps please read our standard documentation<\/a>.<\/p>\n\n\n\n

Contacts<\/h2>\n\n\n\n

Assemblies of multiple bodies that are not fused together but touch each other require contact definitions. All interfaces between bodies are automatically detected and defined as a bonded contact while the simulation is being created. Sliding<\/em> contact and cyclic symmetry<\/em> are also available. For more information about contacts, have a look at this page<\/a>.<\/p>\n\n\n\n

In the physical contacts<\/a> tab, you can define contact pairs of faces or face sets. Physical contacts help to model contact behavior closer to reality. At the beginning of the simulation, the faces need not touch each other, which is why the distance between these faces can be monitored during a nonlinear calculation. If they touch each other, the interaction forces that prevent those faces from interpenetrating are taken into account. <\/p>\n\n\n\n

Physical contacts are only available for nonlinear analysis. The solution methods are available below:<\/p>\n\n\n\n
