Atmospheric Nitrogen Plasma DBD simulations
 

Dear
Does anyone have an experience on atmospheric nitrogen plasma DBD simulations?
Currently I use COMSOL to simulate my problem. I have done 1D simulation with COMSOL with success, but when I try to do 2D simulations I have divergence. I had tried many solutions but without success. I have doubted if COMSOL can do it.
Does anyone do similar simulations with COMSOL?
Can anyone suggest me another software?
Does anyone try to simulate the same problem with ACE-CFD, Plasimo or Usim?
Thanks for your help
