Failed to find consistent initial values

Hi all,

I am doing simulation of tumor tissue ablation using Radiofrequency ablation technique.
I build a 3D thermal-electrical model in COMSOL and can get the respected results.
To reduce the calculating time, I try to use a 2D thermal-electrical model to mimic the ablation process.
The boundary and initial conditions of 2D model are all set as I did in 3D model.
But there is a error showing "Failed to find consistent initial values. Last time step is not converged."
I also tried different extent of mesh method and reset the relative tolerance.
But it still doesn't work.

Does anyone happen to encounter this problem?

Thanks.
