A finite element analysis models how a system responds to the specified loading conditions. You must apply boundary conditions to accurately simulate these conditions. This term refers to the available loads and constraints that can be applied to a component or structure. It is often used interchangeably with loads or supports.

The available boundary conditions depend on the type of analysis you are performing. For example, a stress analysis can involve pressure and force loads and displacements for supports, while a thermal analysis can involve convection and temperature loads.

Boundary conditions can be applied directly, imported, or defined as remote boundary conditions. You select a boundary condition and scope it to your model. You then specify its magnitude and other required information. You can also specify whether a load is stepped or ramped.
