Detailed Description

class Intrepid2::Basis_HGRAD_TET_COMP12_FEM< ExecSpaceType, outputValueType, pointValueType >

Implementation of the default H(grad)-compatible FEM basis of degree 2 on Tetrahedron cell.

Implements Lagrangian basis of degree 2 on the reference Tetrahedron cell. The basis has cardinality 10 and spans a COMPLETE quadratic polynomial space. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows:

Remarks
Ordering of DoFs follows the node order in Tetrahedron<10> topology. Note that node order in this topology follows the natural order of k-subcells where the nodes are located, i.e., L_0 to L_3 correspond to 0-subcells (vertices) 0 to 3 and L_4 to L_9 correspond to 1-subcells (edges) 0 to 5.
