I’m using Garfield++, Gmsh, and Elmer to perform gas amplification simulations of electrons.
I’m referring to the lem example.
The simulation can run to the end, but halfway through I will often get the following message:
MediumMagboltz::GetElectronCollisionRate: Rate at 42.2937 eV is not included in the current table. Increasing energy range to 44.4084 eV. AvalancheMicroscopic::TransportElectron: Increasing null-collision rate by 5%.
What does this message mean and how does it affect the simulation?
I have attached the program I am using.
Appreciate your help.
