Detailed Description

Transform a [0,1]^D mesh into a spiral. The parameters are: turns - number of turns around the origin, width - for D >= 2, the width of the spiral arm, @ gap - gap between adjacent spiral arms at the end of each turn, @ height - for D = 3, the maximum height of the spiral.

◆ Eval() [1/2]

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.

◆ Eval() [2/2]

void mfem::common::SpiralTransformation::Eval	(	Vector &	V,
		ElementTransformation &	T,
		const IntegrationPoint &	ip )

overridevirtual

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.
