Vector coefficient defined as a cross product of two vectors.
Definition at line 1783 of file coefficient.hpp.
mfem::VectorCrossProductCoefficient::VectorCrossProductCoefficient  (  VectorCoefficient &  A, 
VectorCoefficient &  B  
) 
Construct with the two coefficients. Result is A x B.
Definition at line 1101 of file coefficient.cpp.

virtual 
Evaluate the coefficient at ip.
Implements mfem::VectorCoefficient.
Definition at line 1118 of file coefficient.cpp.
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.
Definition at line 222 of file coefficient.cpp.
virtual void mfem::VectorCoefficient::Eval 
Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.
