calc_area_bc()

subroutine calc_area_bc

Calculate the surface "area" of the boundary.

Note

It is not a true area, but merely a count of all points on the boundary.

gij_from_bc()

subroutine gij_from_bc	(	real, dimension(lx1, ly1, lz1, ldim, ldim)	gij,
		integer	ie
	)

Adjust gradient at the boundary using the MOST relation.

planar_avg_horiz()

subroutine planar_avg_horiz	(	real, dimension(lx1,ly1,lz1,lelt)	ua,
		real, dimension(lx1, ly1, lz1, lelt)	u
	)

Compute planar average of quantity u along horizontal directions.

Parameters

[in]	u	Array to be averaged
[out]	ua	Planar average of u

planar_avg_spanwise()

subroutine planar_avg_spanwise	(	real, dimension(lx1,ly1,lz1,lelt)	ua,
		real, dimension(lx1, ly1, lz1, lelt)	u
	)

Compute planar average of quantity u along spanwise direction.

Parameters
