Compute Jacobian J = dX/dη, and returns its determinant.
Compute Jacobian J = dX/deta, and returns its determinant.
FALLBACK default implementation; but if possible implement a faster ad hoc computation.
Implements chrono::fea::ChFieldElement.
Reimplemented in chrono::fea::ChFieldElementTetrahedron4, and chrono::fea::ChFieldElementHexahedron8.
