Electron energy density equation

Hello,
In my model EEDF is very far from maxwellian or druyvesteyn form. So, I define the rates of electron impact reactions via rate constant, not via cross section. The rate constants are the functions of electric field: k(E/N), not of the electron energy. Electron energy equation doesn't important for me in this case.
The question is: is there any possibility to turn of this equation (6-15 in "Plasma_UG.pdf") from the project calculations? Or I have to use the PDE interface?
Thank you,
Vladimir

Hi Vladimir, it is possible to turn off the equation which solves for the electron energy in version 4.1. When you do this, the electron energy is fixed at its initial value. Note that the electron losses to the wall depend on the electron energy so your model will not be truly self consistent if you chose to fix the mean electron energy.
