Member Function Documentation

Eval() [1/2]

real_t mfem::ShiftedFunctionCoefficient::Eval ( ElementTransformation & T, const IntegrationPoint & ip )

inlineoverridevirtual

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.

Eval() [2/2]

real_t mfem::ShiftedFunctionCoefficient::Eval	(	ElementTransformation &	T,
		const IntegrationPoint &	ip,
