I am working with Ansys Classic.
I am trying to calculate thermal stress in aluminium piston engine (it's student's project).
After getting temperature results I want to calculate thermal stress.
I have problem with setting correct boundary conditions (displacements in structural analysis).
When I apply all DOF constrains in pin hole I could find in this area very high stress.
How should I model it?
Should I model pin and apply contact between it and piston?
