Setting of LKT terms when using MF6-generated flow fields #71

Closed emorway-usgs closed 4 years ago

emorway-usgs commented 4 years ago

MT3D-USGS needs to access flowdata in BudgetDataModule in order to set some internal variables that are passed via the linker file when using MF2K5 (MF-NWT) generated flow fields.

@rbwinst-usgs I was able to get this model to run using the two input files attached to this post. The two main adjustments were to (1) drop the LKT file type from the name file and (2) and the LAK cells to the SSM input file. This is a nice test problem and I'd like to add it to our suite of auto-tests run on Travis.

Note that similar consideration will need to be given to SFR with MODFLOW 6-generated linker input. That is to say, you won't use SFT with file type FT6 (MODFLOW 6 linker input), you will need to add these boundary cells to SSM and think of them as boundary only, analogous to RIV, for example. At some point we may revisit support for doing transport in LAK and SFR (and possibly UZF) in MT3D-USGS, but for right now we don't have any readers that can interpret these fluxes from the MODFLOW 6 output.

Closing this issue, but don't hesitate to let me know (or reopen) if you're still having trouble.

This issue is also partially fixed by issue #72 . The model will now stop if users attempt to use LKT in a name file that also uses FT6 (same for UZT and SFT).
