The CoarseFineFlux Subroutine

The CoarseFineFlux subroutine in FixUp sets the fluxes normal to a child grid to zero.

Input Parameters

• n: Refers to the direction of the current slice
• indx: contains the indices for the slice in the n-direction
• extlow: contains the lower index in the n-direction
• exthigh: contains the upper index in the n-direction
• Info%ChildSign1D: contains an integer that is 1 at coarse/fine interfaces, -1 at fine/coarse interaces, and 0 elsewhere

Output Parameters

• Info%numfqr: contains the transverse fluxes in the n-direction at the right edges
• Info%numfql: contains the transverse fluxes in the n-direction at the left edges
