Member Function Documentation

void mfem::VectorFunctionCoefficient::Eval ( Vector V,
ElementTransformation T,
const IntegrationPoint ip 
)
virtual

Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.

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).

Implements mfem::VectorCoefficient.
