void mfem::VectorQuadratureFunctionCoefficient::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.

void mfem::VectorQuadratureFunctionCoefficient::SetComponent ( int  _index,
int  _length 
)

Set the starting index within the QuadFunc that'll be used to project outwards as well as the corresponding length. The projected length should have the bounds of 1 <= length <= (length QuadFunc - index).
