Member Function Documentation

◆ GetRule()

TPZGaussRule * TPZIntRuleList::GetRule	(	int	order,
		int	type = `0`
	)

Returns a pointer to an gaussian integration rule with numint points. This method computes the number of points to right Gaussian quadrature.

Parameters

order	Degree of the polinomial for which the integration is exact.
type	Type values: 0 - Gauss Legendre (default), 1 - Gauss Lobatto, 2 - Gauss Jacobi
