virtual const VecIndex& FEOrthoMeshDealWrapper::face_to_cell_local_map

(

Index

faceId

)

[inline, virtual]

Implements FiniteElementInterface.

Definition at line 54 of file feorthomeshdealwrapper.h.

  {
    return _face_to_cell_map[faceId];
  }

virtual const ArrayOfVecDouble& FEOrthoMeshDealWrapper::get_support_points

(

)

[inline, virtual]

Get the support points for each local dof on the reference element. So the support point of the nth local dof is return as a 3d point on the nth position of the ArrayOfVecDouble.

Definition of support points: In many finite elements, each degree of freedom, ak represents the value of the function a0*N0(xi) + a1*N1(xi) .... an*Nn(xi) at a specific point xi==xk. This xk is the support point of the dof ak.

In the vector returned from this function the position i of this vector has the support point of the local dof i in the reference domain.

Implements FiniteElementInterface.
