NEUTRAL_FULL_VELOCITY_H#
struct NeutralFullVelocity : public Component#
#include <neutral_full_velocity.hxx>

Neutral gas model, evolving three components of velocity as axisymmetric fields

Evolves neutral density, pressure and velocity as Field2D quantities

Public Functions

NeutralFullVelocity(const std::string &name, Options &options, Solver *solver)#
virtual void finally(const Options &state) override#

Use the final simulation state to update internal state (e.g. time derivatives)

Use the final simulation state to update internal state (e.g. time derivatives) Note: The evolving state (density, temperature, pressure, velocity) is not taken from state. These are calculated in transform() that must be called before finally().

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#

Modify the given simulation state.
