Joule heating error implementing insulator

Hi,

I'm new here and quite desperate. I try to simulate the heat distribution between 2 conductors separated by a glass insulator. The moment I apply SiO2 as material the simulation stops working. If I change to another material, it's okay again - of course the results are useless. There seems to be no missing parameter in SiO2. What could be the problem?

André,

if you are using the ec application mode, you should give the insulator a very small electrical conductivity to improve the stability of the solver.

Cheers
Edgar

Hi,

thanks for the quick reply. It actually works if I set the conductance to a finite, but low value. Didn't think so, since the heat transport simulation works and the electrical conductance would have just insulated the interface. Thanks for the tip!
