BINORMAL_STPM_H

struct BinormalSTPM : public Component 

#include <binormal_stpm.hxx>

Adds terms to Density, Pressure and Momentum equations following the stellarator 2-point model from Yuhe Feng et al., PPCF 53 (2011) 024009 The terms add the effective parallel contribution of perpendicular transport which is of significance in long connection length scenarios.
