SHEATH_BOUNDARY_INSULATING_H

struct SheathBoundaryInsulating : public Component 

#include <sheath_boundary_insulating.hxx>

Insulating sheath boundary condition at the wall in Y

This is a collective component, because it couples all charged species

Adapted from the sheath_boundary component, but always sets the current density to zero

Public Functions

SheathBoundaryInsulating(std::string name, Options &options, Solver*)

virtual void transform(Options &state) override

Inputs

species
- e
  - density
  - temperature
  - pressure Optional
  - velocity Optional
  - mass Optional
  - adiabatic Optional. Ratio of specific heats, default 5/3.
- <ions> if charge is set (i.e. not neutrals)
  - charge
  - mass
  - density
  - temperature
  - pressure Optional
  - velocity Optional. Default 0
  - momentum Optional. Default mass * density * velocity
  - adiabatic Optional. Ratio of specific heats, default 5/3.
fields
- phi Optional. If not set, calculated at boundary (see note below)

Outputs

species
- e
  - density Sets boundary
  - temperature Sets boundary
  - velocity Sets boundary
  - energy_source
- <ions>
  - density Sets boundary
  - temperature Sets boundary
  - velocity Sets boundary
  - momentum Sets boundary
  - energy_source
fields
- phi Sets boundary

If the field phi is set, then this is used in the boundary condition. If not set, phi at the boundary is calculated and stored in the state. Note that phi in the domain will not be set, so will be invalid data.
