Recently updated CALC_XSA routine in MF-NWT #19

Closed emorway-usgs closed 5 years ago

emorway-usgs commented 6 years ago

With commit 0c3902f in MF-NWT, we're now using the flow out of a reach to calculate the cross-sectional area. Prior to this fix, we were using the inflow to the reach to calculate cross-sectional area. This change will likely change the solutions is some of the auto-tests that employ SFT. As this issue states, negative values for FLOW in item 4b of the SFR input (see the Online guide to MODFLOW) were never tested. However, J White was running into issues with negative values for FLOW specified in one of his models.

See commit 65cba38 on the MF-NWT repo for an update to this. Also refer to issue #13 on MF-NWT repo. There is a test model (jeremy's) attached to that issue for testing the code with.
