mfem::TElementTransformation< Mesh_t, IR, real_t > Class Template Reference

Element transformation class, templated on a mesh type and an integration rule. It is constructed from a mesh (e.g. class TMesh) and shape evaluator (e.g. class ShapeEvaluator) objects. Allows computation of physical coordinates and Jacobian matrices corresponding to the reference integration points. The desired result is specified through the template subclass Result and stored in an object of the same type. More...

Detailed Description

template<typename Mesh_t, typename IR, typename real_t = double>
class mfem::TElementTransformation< Mesh_t, IR, real_t >

Element transformation class, templated on a mesh type and an integration rule. It is constructed from a mesh (e.g. class TMesh) and shape evaluator (e.g. class ShapeEvaluator) objects. Allows computation of physical coordinates and Jacobian matrices corresponding to the reference integration points. The desired result is specified through the template subclass Result and stored in an object of the same type.

template<typename Mesh_t , typename IR , typename real_t = double>
enum mfem::TElementTransformation::EvalOperations

Enumeration for the result type of the TElementTransformation::Eval() method. The types can obtained by summing constants from this enumeration and used as a template parameter in struct Result.
