Vector coefficient defined as the Curl of a vector GridFunction.
Definition at line 890 of file coefficient.hpp.
mfem::CurlGridFunctionCoefficient::CurlGridFunctionCoefficient  (  const GridFunction *  gf  ) 
Construct the coefficient with a vector grid function gf. The grid function is not owned by the coefficient.

Definition at line 911 of file coefficient.hpp.
virtual void mfem::VectorCoefficient::Eval 
Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.
void mfem::VectorCoefficient::Eval 
Evaluate the vector coefficient in the element described by T at all points of ir, storing the result in M.
The dimensions of M are GetVDim() by ir.GetNPoints() and they must be set by the implementation of this method.
The general implementation provided by the base class (using the Eval method for one IntegrationPoint at a time) can be overloaded for more efficient implementation.
