Contacts are necessary in cases when the simulation domain doesn’t consist of one part – built from a single material, but an assembly of parts, often built from different materials, and even combining fluids and solids in the case of multi-physics simulations. A realistic model requires a setup where the relations between the multiple components are fully defined.<\/p>\n\n\n\n
SimScale accepts multi-part models for simulation in the following domains:<\/p>\n\n\n\n
In terms of contact definitions, solid mechanics simulations include:<\/p>\n\n\n\n
For these simulations, a distinction is made between linear and non-linear (physical) contacts. Linear contacts work under the assumption that the parts remain bonded or have small relative deformations, while non-linear contacts can take into account large sliding, separation and collision between the parts.<\/p>\n\n\n\n
In the following pages, the details on the modeling and setup of contacts and solid mechanics are given:<\/p>\n\n\n\n
