SIMPInterpolationCoefficient()

Eval()

virtual double mfem::SIMPInterpolationCoefficient::Eval ( ElementTransformation &  T, const IntegrationPoint &  ip  )

inlinevirtual

Evaluate the coefficient in the element described by T at the point ip.

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::Coefficient.
