BRAGINSKII_FRICTION_H#
struct BraginskiiFriction : public Component#
#include <braginskii_friction.hxx>

Calculates the friction force applied to each species due to collisions.

Public Functions

BraginskiiFriction(const std::string &name, Options &alloptions, Solver*)#

  • frictional_heating Include R dot v heating term as energy source? (includes Ohmic heating)

Parameters:

alloptions – Settings, which has switches for additional terms:

virtual void outputVars(Options &state) override#

Add extra fields for output, or set attributes e.g docstrings.

Private Functions

virtual void transform_impl(GuardedOptions &state) override#

Calculate transfer of momentum and energy between species due to friction arising from collisions.

Uses
