Detailed Description
template<class Scalar, class ArrayScalar>
class Intrepid::Basis_HGRAD_TET_C2_FEM< Scalar, ArrayScalar >
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:
================================================================================================= | | degree-of-freedom-tag table | | | DoF |----------------------------------------------------------| DoF definition | | ordinal | subc dim | subc ordinal | subc DoF ord |subc num DoF | | |=========|==============|==============|==============|=============|===========================| | 0 | 0 | 0 | 0 | 1 | L_0(u) = u(0,0,0) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 1 | 0 | 1 | 0 | 1 | L_1(u) = u(1,0,0) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 2 | 0 | 2 | 0 | 1 | L_2(u) = u(0,1,0) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 3 | 0 | 3 | 0 | 1 | L_3(u) = u(0,0,1) | |---------|--------------|--------------|--------------|-------------|---------------------------| |---------|--------------|--------------|--------------|-------------|---------------------------| | 4 | 1 | 0 | 0 | 1 | L_4(u) = u(1/2,0,0) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 5 | 1 | 1 | 0 | 1 | L_5(u) = u(1/2,1/2,0) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 6 | 1 | 2 | 0 | 1 | L_6(u) = u(0,1/2,0) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 7 | 1 | 3 | 0 | 1 | L_7(u) = u(0,0,1/2) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 8 | 1 | 4 | 0 | 1 | L_8(u) = u(1/2,0,1/2) | |---------|--------------|--------------|--------------|-------------|---------------------------| | 9 | 1 | 5 | 0 | 1 | L_9(u) = u(0,1/2,1/2) | |=========|==============|==============|==============|=============|===========================| | MAX | maxScDim=0 | maxScOrd=3 | maxDfOrd=0 | - | | |=========|==============|==============|==============|=============|===========================|
- 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.
