### Discountinuities on surface net current and flux

The surface fluxes and currents on same surface shared by two neighboring GCU have different values.
Is it possible to fix this problem?

### Re: Discountinuities on surface net current and flux

Could you provide more information on your problem? It is impossible to say anything based on this report. What values did you compare? Detector values or values provided by set adf card? What are the boundary surfaces of the to universes to be homogenized? Are you comparing heterogeneous or homogeneous surface fluxes? The surface currents and heterogeneous surface fluxes should have same values on a shared boundary.

### Re: Discountinuities on surface net current and flux

Values provided by set adf card.
here are lines copied from output,
DF_SURFACE (idx, [1: 3]) = '102' ;

The last two net currents of '102', 3.00178E-03 and 4.64663E-03 are for top of cell.
the corresponding curents of '103', -3.00177E-03 and -4.64661E-03.

there are not too much difference, but can be more significant for other cases.

I will provide my input here

### Re: Discountinuities on surface net current and flux

How large are the maximum differences that you see? The routine that scores the ADF currents checks the position where the boundary is crossed. This is not 100% accurate near the edges and corners, so there maybe some random inconsistencies between the corresponding inward and outward currents.

### Re: Discountinuities on surface net current and flux

sorry for late response. The maximum difference I saw was about 1.0E-4, not very large, but large enough to be noticeable.
