◀ Back to enriched Galerkin definition page
- \(R\) is the reference tetrahedron. The following numbering of the subentities of the reference is used:
- Basis functions:
\(\displaystyle \phi_{0} = - x - y - z + 1\)
\(\displaystyle \phi_{1} = x\)
\(\displaystyle \phi_{2} = y\)
\(\displaystyle \phi_{3} = z\)
\(\displaystyle \phi_{4} = 1\)
