Detailed Description

Vector coefficient defined as a normalized vector field (returns v/|v|)

Definition at line 1693 of file coefficient.hpp.

Constructor & Destructor Documentation

mfem::NormalizedVectorCoefficient::NormalizedVectorCoefficient	(	VectorCoefficient &	A,
		double	tol = 1e-6
	)

Return a vector normalized to a length of one.

This class evaluates the vector coefficient A and, if |A| > tol, returns the normalized vector A / |A|. If |A| <= tol, the zero vector is returned.

Definition at line 962 of file coefficient.cpp.
