Idomain function for disV-grids

[Groundwater-modeler]

Hi,

I'm looking for an equivalent to the flopy.mf6.MFSimulation.load(sim_ws="").get_model("model_name").dis.idomain.array[0] for unstructured disV grids.

I tried to use the .grb-file but failed. What i want to achieve is to read in the active portion of my model rather than the whole grid. Any ideas?
