Detailed Description

The PeriodicBCModel implements periodic boundary conditions specifically designed for rectangular unit cells. It supports multiple operation modes including load control, displacement control, and gradient updates.

Features:

• Three operation modes: LOAD, UPD (update), and DISP (displacement)
• Automatic corner constraint handling
• Master-slave edge DOF pairing for periodicity
• Gradient-based deformation control
• Support for rotational DOFs

Note

Only works for rectangular unit cells
