struct Recycling : public Component
- #include <recycling.hxx>
Convert fluxes of species at boundaries
Since this must be calculated after boundary fluxes (e.g. sheath), it is included as a top-level component
Public Functions
-
Recycling(std::string name, Options &alloptions, Solver*)
Inputs
<name>

-
Field3D energy_flow_ylow
-
Field3D energy_flow_xlow
Cell edge fluxes used for calculating fast recycling energy source.
-
Field3D particle_flow_xlow
Radial wall particle fluxes for recycling calc. No need to get poloidal from here, it’s calculated from sheath velocity.
-
Field2D is_pump
1 = pump, 0 = no pump. Works only in SOL/PFR. Provided by user in grid file.
