I have faced with the following problem.
I'm trying to solve balance equation for electrons (i.e. calculate electron density) using PDE module (because it's convenient way for my simple model). Parameters in my model are quantities derived from the Boltzmann equation (BE).
Earlier I tried to solve BE in the parametric sweep regime and then create 2D plots for all parameters I need (rate coefficients depending on electrical field and electron density) and put these graphs in my PDE module. I didn't succeed.
Now I'm wondering is there a way to calculate these rate coefficients for particular electrical field and electron density automatically when my PDE module asks for it?
Scheme is following: PDE with initial parameters -> boltzmann equation is solved for these parameters -> comsol puts rate coefficients in PDE -> and so on.
Furthermore, Boltzmann equations is solved on a simple interval [0,100]. PDE module works on axisymmetric geometry. That means that I use different components (comp1 for BE and comp2 for PDE)
Thank you!
