Is it possible to solve the contact pressure in the time-dependent solver

Please login with a confirmed email address before reporting spam

I want to model a contact problem, I need the contact pressure to be used in the another time dependent problem(heat transfer). The parametric solver solves the contact pressure perfectly, but when combining the time dependent solver, I also need to solve the contact pressure in a time dependent solver. I got some help from comsol to use the quasi-static solver in contact preblem, but can the contact pressure be solved with such a solver, I tried some settings but seems no solution. Any body who knows about it , please offer some help.

I think it is possible to solve the contact problem first, then use the result which is pressure here as initial values for the time dependent problem, but I do not know how to couple the solvers, because the augmented lagrangian solver solves the contact problem and the bdf solver or generalized alpha solver solves the time dependent problem, and I can only use one solver at one time, does anybody know how to couple these solvers?
