schwarz Module Reference

Overlapping schwarz solves.

Data Types
type	schwarz_t

Functions/Subroutines
subroutine	schwarz_init (this, xh, dof, gs_h, bclst, msh)
subroutine	schwarz_free (this)
subroutine	schwarz_setup_wt (this)
	setup weights
subroutine	schwarz_setup_schwarz_wt2d_2 (wt, ie, n, work, nelv)
	Setup schwarz weights, 2d, second step.
subroutine	schwarz_setup_schwarz_wt3d_2 (wt, ie, n, work, nelv)
	Setup schwarz weights, 3d, second step.
subroutine	schwarz_toreg3d (b, a, n, nelv)
	convert array a from extended size to regular
subroutine	schwarz_toext3d (a, b, n, nelv)
	convert array a from original size to size extended array with border
subroutine	schwarz_extrude (arr1, l1, f1, arr2, l2, f2, nx, ny, nz, nelv)
	Sum values along rows l1, l2 with weights f1, f2 and store along row l1. Helps us avoid complicated communcation to get neighbor values. Simply copy interesting values to the boundary and then do gs_op on extended array.
subroutine	schwarz_extrude_single (arr, l1, f1, l2, f2, nx, ny, nz, nelv)
	Same as schwarz_extrude but for the case when arr1 and arr2 are the same array. Avoids aliasing by using a single dummy argument. l1 and l2 must index non-overlapping rows (e.g. 0 vs 2).
subroutine	schwarz_compute (this, e, r)
subroutine	schwarz_wt3d (e, wt, n, nelv)

schwarz_compute()

Here is the call graph for this function:

schwarz_extrude()

subroutine schwarz::schwarz_extrude ( real(kind=rp), dimension(nx, ny, nz, nelv), intent(inout)  arr1, integer, intent(in)  l1, real(kind=rp), intent(in)  f1, real(kind=rp), dimension(nx, ny, nz, nelv), intent(in)  arr2, integer, intent(in)  l2, real(kind=rp), intent(in)  f2, integer, intent(in)  nx, integer, intent(in)  ny, integer, intent(in)  nz, integer, intent(in)  nelv  )

private

Note

arr1 and arr2 must not be the same array. Use schwarz_extrude_single when operating on a single array to avoid aliasing violations.
