Calculate electron heat flux using the Shurtz-Nicolai-Busquet (SNB) model
This component will only calculate divergence of heat flux for the electron (
e) species.Usage
Add as a top-level component after both electron temperature and collision times have been calculated.
Important: If evolving electron pressure, disable thermal conduction or that will continue to add Spitzer heat conduction.
[hermes] components = e, ..., collisions, snb_conduction [e] type = evolve_pressure, ... thermal_conduction = false # For evolve_pressure [snb_conduction] diagnose = true # Saves heat flux diagnostics
