Detailed Description

template<int dim>
class PHiLiP::FEValuesShapeHessian< dim >

Class to evaluate hessians of shape functions w.r.t. physical quadrature points.

This class is designed for computing shape hessians w.r.t. the physical domain defined by MappingFEField (with volume nodes vector in HighOrderGrid).
