Thermal Expansion

Please login with a confirmed email address before reporting spam

Hello,

I want to simulate thermal expansion for a thin 2D plate. For that, I use the "Thermal Expansion" Multiphysics module, which couples the "Solid Mechanics" and "Heat transfer in Solids" interfaces.

The boundary conditions for the Solid Mechanics interface are: - Fixed load at the plate edges.

The 2D plate is centrally heated by a laser beam using the "Deposited Beam Power" interface.

The boundary conditions for the thermal load are: - Constant temperature at the plate edges. - Central heating.

Unfortunately, the solution (Study 1 in attached model) doesn't converge.

Could someone tell me why?

Thanks,
