LAK3 postprocessing in Flopy

[joaravena]

Hi everyone!
I'm trying to postprocess a transient simulation from Groundwater Vistas using MODFLOW-NWT and the LAK3 package in FloPy, but I keep encountering the following error when trying to import the model file:

"File C:...\flopy\modflow\mflak.py:720 in load
stage_range.append((float(t[ipos]), float(t[ipos + 1])))

IndexError: list index out of range""

I was able to postprocess the same model in steady-state mode without any issues, but doing it for the transient case has been much more difficult.

Has anyone experienced this or knows what might be causing it?

Thanks in advance!
Joaquín

This code block has coverage, but it may miss formatted LAK files (it only tests free format). Is it possible to load a few of the simulation files? Probably just nam, dis, bas and lak files will do.
