Direct Thermal-Structural Coupling with ACT Object
The ANSYS App store has a free ACT object that can be downloaded and installed in Workbench to enable several direct coupling capabilities. This video illustrates its use to obtain direct thermal-structural coupling, letting elements carry both thermal and displacement degrees of freedom.
One use would be in models in which thermal expansion causes contacts to open or close with sudden cut-off or turn-on of thermal contact and heat flow. In this video, the use of a joint in a model that simultaneously has structural displacement and heat transfer is illustrated.
