Time dependent solution?

Please login with a confirmed email address before reporting spam


Hello!

I’m trying to solve a Thermal-Structural Interaction using predefined multiphysics coupling that adds both a Plane Strain and a heat transfer application mode.
I want to define strains and loads that are constant in time and see the thermal and structural changes in time.
At first I thought of using a transient (time dependent analysis) but solving the problem the time dependent solver remained on 0% and the model could not be solved. Using a static analysis a solution was accomplished. However, a static solution is not what I desire… I’ve tried to use the quasi-static transient analysis… but the solver that was chosen by comsol as default was the static one… (again, the model was solved) but as I chosen the time dependent solver still the time dependent solver remained on 0% and the model wasn’t solved.

How can I overcome this difficulty? Must I define loads or strains which are time dependant in order to get a time dependent solution?
