The Tutorial used during DSD 2025 makes use of the PRJ file iMOD5_model.prj.
This file contains the section "Species". This section is not empty, it contains "benzene",1
The function imod.prj.read_projectfile reads the PRJ file with the Species information. It includes this Species information in the function-return-data, a Dictionary.
iMOD Python is compatible with iMOD5 quantity models. It doesn't support (yet) reading the PRJ file containing a ground water quality model.
Suggestion: for now leave the Species information out of the return Dictonary to prevent causing confusion.
