Description

This lecture covers the concept of using symmetries in Finite Element (FE) models to reduce model size, simplify boundary conditions, and post-processing effort. It explains how symmetries help in interpreting and reducing rigid-body motions, demonstrating the 3-2-1 trick for setting isostatic boundary conditions. The lecture also includes examples and exercises on applying symmetries, using cylindrical coordinate systems, and dealing with rigid-body motions in FE models.
