◆ Eval() [1/3]

void mfem::VectorCoefficient::Eval ( DenseMatrix M,
ElementTransformation T,
const IntegrationRule ir 
)
virtual

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.

Note
The IntegrationPoint associated with T is not used, and this method will generally modify this IntegrationPoint associated with T.

Reimplemented from mfem::VectorCoefficient.

Definition at line 605 of file coefficient.cpp.

◆ Eval() [2/3]

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

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.

Definition at line 179 of file ex37.hpp.

◆ Eval() [3/3]

virtual void mfem::VectorCoefficient::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.
