Convergence problem in Joule Heating

Please login with a confirmed email address before reporting spam

Hi,
I am trying to perform a stationary simulation about Joule Heating using the Electric currents and the Heat Transfer modules. I am using also a material with a specific Electrical conductivity - Temperature dependance, specified using ad interpolation function.
Problems arise when I run simulations with a fixed current higher than 700uA because the solver seems to oscillates between two solutions and it does not converge.
Any help would be really appreciated. Thank you.

I am not able to attach the file because I get 'file extension error'
