Thermal and structural loads:
You can perform coupled-field analyses using a System Coupling component system in Workbench. Specifically, you can set up a one-way or two-way fluid-structure interaction (FSI) analysis or thermal-structural analysis by connecting a System Coupling component system to Mechanical, Fluent, and External Data systems.
