Member Function Documentation

◆ Eval()

void HRHessianCoefficient::Eval ( DenseMatrix & K,
ElementTransformation & T,
const IntegrationPoint & ip )
inlineoverridevirtual

Evaluate the matrix coefficient in the element described by T at the point ip, storing the result in K.

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::MatrixCoefficient.

◆ EvalGrad()

void HRHessianCoefficient::EvalGrad ( DenseMatrix & K,
ElementTransformation & T,
const IntegrationPoint & ip,
int comp )
inlineoverridevirtual

Evaluate the derivative of the matrix coefficient with respect to comp in the element described by T at the point ip, storing the result in K.

Implements mfem::TMOPMatrixCoefficient.
