Function/Subroutine Documentation

◆ dwlimiter2()

subroutine mod_limiter::dwlimiter2	(	double precision, dimension(ixi^s), intent(in)	dwC,
		integer, intent(in)	ixI,
		integer, intent(in)	L,
		integer, intent(in)	ixC,
			L,
		integer, intent(in)	idims,
		integer, intent(in)	typelim,
		double precision, dimension(ixi^s), intent(out), optional	ldw,
		double precision, dimension(ixi^s), intent(out), optional	rdw,
		double precision, intent(in), optional	a2max
	)

Limit the centered dwC differences within ixC for iw in direction idim. The limiter is chosen according to typelim.

Note that this subroutine is called from upwindLR (hence from methods like tvdlf, hancock, hll(c) etc) or directly from tvd.t, but also from the gradientS and divvectorS subroutines in geometry.t Accordingly, the typelim here corresponds to one of limiter or one of gradient_limiter.

Parameters

[out]	ldw	Result using left-limiter (same as right for symmetric)
[out]	rdw	Result using right-limiter (same as left for symmetric)
