Gauss()

Gauss

(

size_t

np

)

Constructor using number of Gauss points.

Parameters

[in]

np

Number of integration points

Member Function Documentation

setTriangle()

void setTriangle	(	LocalVect< real_t, 7 > &	w,
		LocalVect< Point< real_t >, 7 > &	x
	)

Choose integration on triangle (7-point formula)

If this is not selected, Gauss integration formula on [-1,1] is calculated.

Parameters

[out]	w	Array of weights of integration points
[out]	x	Array of coordinates of integration points
