Solver error joule/mechanics

Hello,
I simulated a copper coil in joule heating and solid mechanics mode.
(similar like the Tutorial bushbar )
The material is temperature dependent.
When I try to solve the problem I alwys get the same Problem :
-----------------------------------------------------------------------------------------------------------------
Error Stationary Solver 1 (sol 1 /s1)
Undefined value found
There are 5734 degrees of freedom giving NaN/Inf in the vector for the variable mod1.u
-----------------------------------------------------------------------------------------------------------------
Now my question is how can I solve this problem. Is the problem the solver or anithing else.
When i enable the mechanics part the solution is no problem but all two together does not run.
Thank´s

Hi
these kind of errors remind me rather of missing BC (boundary conditions) or variables (specially the indirect ones suc as material temperature and pressure that comes "hidden" if you use th library material.
you should start by trying to initialise your model with only the initial conditions "3.5: SOLVE>get initial values" if this fails your model is not complete and should be rechecked

Good luck
