Support for Steady State MT3DMS Mode

[AKoehler95]

Hi everyone,

I was wondering if there is support for the steady state mode for transport modeling as mentioned in the MT3DMS manual for version 5.3, chapter 10 (https://hydro.geo.ua.edu/mt3d/mt3dms_v5_supplemental.pdf) in flopy.
In the documentation I could not find a "steady state" argument for the BTN module and was wondering if this can be done or if the period length must be adjusted to some sufficiently long time.
Thanks in advance!

Cheers,
Anton

I checked the source code today and the ssflag argument does exist for the BTN module, but was not added to the documentation. Here's an example of how to use it:

ssflag = ["ssflag"] + ["" for _ in range(kper - 1)]
btn = Mt3dBtn(..., ssflag=ssflag)
 # or if your btn file already exists you can use
btn.ssflag = ssflag

Thank you, works now!
