Time dependent study with Joule heating and thermal expansion physics

Please login with a confirmed email address before reporting spam

Dear Sir,
I have made two 2D geometries using Joule heating and thermal expansion physics. I am using time dependent study. So the actuation electric potential is provided using the 'Piecewise Function'. My problem is that when I am increasing the size of the geometry, its not getting converged and error is coming after a long time simulation. I have given the mesh with better resolution and tried with both segregated and fully coupled solvers. Also to avoid the stress at the edges I used fillets.

. Please guide me to overcome these problems.

Thanking you,
Joshitha C
