Difference between "Log" and "Linear" equation formulation, Plasma module

Hi everyone, I have a question which couldn't find any answer in the documents. I'm modeling positive corona discharge in plasma module. The documents of software suggest to set the "Equation...

Re: Difference between "Log" and "Linear" equation formulation, Plasma module

Hi Peyman, for the same initial conditions, the log and linear formulations should give the same results. The log formulation is the default option because it prevents negative values for the electron...

Re: Difference between "Log" and "Linear" equation formulation, Plasma module

It's been a while since I posted this topic, but I realized later that the difference between two formulations actually is the fact that the log formulation has stabilization term term which adds...
