Member Function Documentation

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

A VectorDeltaFunction cannot be evaluated. Calling this method will cause an MFEM error, terminating the application.

Implements mfem::VectorCoefficient.

Definition at line 520 of file coefficient.hpp.

void mfem::VectorDeltaCoefficient::EvalDelta ( Vector V,
ElementTransformation T,
const IntegrationPoint ip 
)

Return the specified direction vector multiplied by the value returned by DeltaCoefficient::EvalDelta() of the associated scalar DeltaCoefficient.

void mfem::VectorDeltaCoefficient::GetDeltaCenter ( Vector center)
inline

Definition at line 510 of file coefficient.hpp.

DeltaCoefficient& mfem::VectorDeltaCoefficient::GetDeltaCoefficient ( )

inline

Definition at line 509 of file coefficient.hpp.

void mfem::VectorDeltaCoefficient::SetDeltaCoefficient ( const DeltaCoefficient _d)
inline

Replace the associated DeltaCoeficient with a new DeltaCoeficient.

The new DeltaCoeficient cannot have a specified weight Coefficient, i.e. DeltaCoeficient::Weight() should return NULL.
