Member Function Documentation

double mfem::TransformedCoefficient::Eval ( ElementTransformation T,
const IntegrationPoint ip 

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

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).

Implements mfem::Coefficient.
