Integration scheme for mesh triangle interiors

Usage

fm_int_mesh_2d_core(mesh, tri_subset = NULL, nsub = NULL)

Arguments

mesh: Mesh on which to integrate
tri_subset: Optional triangle index vector for integration on a subset of the mesh triangles (Default NULL)
nsub: number of subdivision points along each triangle edge, giving (nsub + 1)^2 proto-integration points used to compute the vertex weights (default nsub=9, giving 100 integration points for each triangle)

Value

list with elements loc and weight with integration points for the mesh
