Intrepid::Basis_HDIV_TET_In_FEM< Scalar, ArrayScalar > Class Template Reference

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: More...

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:

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.
