AnisoMortarExchange_MappedVector3D Subroutine

  1. SELF_MappedVector_3D.f90
  2. SELF_MappedVector_3D
  3. AnisoMortarExchange_MappedVector3D

public subroutine AnisoMortarExchange_MappedVector3D(this, mesh)

GPU implementation of the vector anisotropic mortar exchange; the kernels treat the (variable, direction) pairs as 3*nvar independent trace lines.
