Member Function Documentation

set()

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void eb_cut_cell_::path_data::set ( const amrex::RealVect &  eb_point, const amrex::RealVect &  eb_normal, const amrex::RealVect &  v_start, const amrex::RealVect &  v_end  )

inline

Compute and store the intersection data for one edge.

Parameters

eb_point	Point on the EB plane.
eb_normal	Unit normal for the EB plane.
v_start	First endpoint of the edge.
v_end	Second endpoint of the edge.
