Detailed Description
template<class Scalar, class ArrayScalar>
class Intrepid::Basis_HDIV_TET_In_FEM< Scalar, ArrayScalar >
Implementation of the default H(div)-compatible Raviart-Thomas basis of arbitrary degree on Tetrahedron cell. The lowest order instance starts with n. Implements the nodal basis of degree n the reference Tetrahedron cell. The basis has cardinality n(n+1)(n+3)/2 and spans an INCOMPLETE polynomial space of degree n. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows:
- The normal component on a lattice of order n+1 and offset 1 on each face (see PointTools). This gives one point per edge in the lowest-order case. These are the first 4 * (n*(n+1)/2) degrees of freedom.
- If n > 1, the x and y z components at a lattice of order n+2 and offset on the interior of the tetrahedron. These are the rest of the degrees of freedom.
If the pointType argument to the constructor specifies equispaced points, then the face and interior points will be equispaced. If the pointType argument specifies warp-blend points, the interior of a warp-blend lattice will be used on each face and also for the cell interior.
