I have an element made of a polymer. I have the temperature dependence of viscosity, heat conductivity, etc.
How can I create model for simulation of the changing shape of the item (gravity) at the time of increasing temperature.

Regards,
RaK

Hi

I would say use a body load of the type (rho*g_const) [N/m^3] and run a temperature sweep, so you need to solve for either u,v,w (displacements) and T or u,v,w (velocities) and T

Good luck
