Member Function Documentation

virtual double mfem::Coefficient::Eval ( ElementTransformation &  T, const IntegrationPoint &  ip  )

pure virtual

Evaluate the coefficient in the element described by T at the point ip.

Note

When this method is called, the caller must make sure that the IntegrationPoint associated with T is the same as ip. This can be achieved by calling T.SetIntPoint(&ip).

Implemented in mfem::DeterminantCoefficient, mfem::VectorRotProductCoefficient, mfem::InnerProductCoefficient, mfem::PowerCoefficient, mfem::ProductCoefficient, mfem::SumCoefficient, mfem::ExtrudeCoefficient, mfem::DivergenceGridFunctionCoefficient, mfem::RestrictedCoefficient, mfem::DeltaCoefficient, mfem::electromagnetics::JouleHeatingCoefficient, mfem::TransformedCoefficient, mfem::GridFunctionCoefficient, mfem::FunctionCoefficient, mfem::PWConstCoefficient, mfem::ConstantCoefficient, mfem::electromagnetics::ScaledGFCoefficient, and mfem::electromagnetics::MeshDependentCoefficient.

double mfem::Coefficient::Eval ( ElementTransformation &  T, const IntegrationPoint &  ip, double  t  )

inline

Evaluate the coefficient in the element described by T at the point ip at time t.

Note

When this method is called, the caller must make sure that the IntegrationPoint associated with T is the same as ip. This can be achieved by calling T.SetIntPoint(&ip).
