Selecting the Physics Interface
The structural mechanics products contain a number of physics interfaces for a wide range of applications. This section contains some guidelines for how to select an appropriate physics interface for your analysis.
The basic physics interfaces for structural mechanics are:
Solid Mechanics—General modeling of objects with extension in all directions
Shell and Plate—For objects which are thin in one direction, but have significant bending stiffness
Membrane—For objects which are thin in one direction, and have negligible bending stiffness
Beam—For objects where two directions have significantly smaller dimensions than the third; significant bending stiffness
Truss—For objects where two directions have significantly smaller dimensions than the third; only axial forces can be transmitted
