Make usr_mug backward compatible with mfix-25.3

Hi,

usr_mug = .T. is supposed to be backward compatible (check_data/check_gas_phase.f) but the GUI is unhappy and cannot load a *.dat or *.mfx file when it is present. It is OK to select instead MU_G_MODEL = .T. instead and that works. Just a wee note.

Thanks Eric. That’s what we call an “oops” :slight_smile:

Line 743 in project_manager.py is incorrect. Instead of self.unset_keyword it should be self.gui.unset_keyword. You can fix this in-place by editing $CONDA_PREFIX/lib/python3.13/site-packages/mfixgui/project_manager.py

This will be fixed for the next release (26.1). Thanks as always for the report.
