When running the program, the terminal displays the following statement:
MediumMagboltz::GetElectronCollisionRate:
Rate at 213.998 eV is not included in the current table.
Increasing energy range to 224.698 eV.
AvalancheMicroscopic::TransportElectron: Increasing null-collision rate by 5%.
Is this because the electron energy is too high? Is the gas file data inappropriate? How to solve this problem?
It’s not necessary a problem. MediumMagboltz doesn’t know anything about the electric field in which the electrons will drift (and hence their energies), so it makes a default guess for the electron energy range. If an electron exceeds this range, the upper limit is increased and the cross-section table is reloaded. You can suppress/avoid this by setting the energy explicitly upfront (SetMaxElectronEnergy).
