modelgrid class (possible bug?)

[DStrom1987]

I apologize in advance for starting another thread on a possibly already answered topic.

I still dont quite understand why the modelgrid function doesnt work for me...

I have been looking at the example i the image below.

I tried to use the same procedure for my own data, but for whatever reason the modelgrid returns an attribute error.

using the following line of code I have atleast been able to access the grid information:

sr = flopy.discretization.vertexgrid.VertexGrid.from_binary_grid_file(grb_name, verbose=False)

Why cant I access my model with the modelgrid class?

Sincerely
David

@DStrom1987 check the sim.model_names property to see if a model "mod0000" really exists in your simulation?

[DStrom1987]

hmm, it does not return None.

Same goes for another case.

MFSimulation does not have a modelgrid property, only the model. In your case vertex_sim is a simulation, not a model.

[DStrom1987]

my bad. Still, same happens if i try and load in the vertex_m (i.e. the model) in such manner as in the example.

edit: turns out print(vertex_m) returns None after all.. Dont really know why? All that is going on is
sim = flopy.mf6.MFSimulation.load(sim_ws=tmp_d, verbosity_level=0) and m = sim.getmodel("modelname")

It looks like your model name is "modflow", try using that name. If you only have one model in your simulation, you can also use get_model() without providing a name.

that did it! How strange.. The models name is disv as far as I can tell. Which is what I named it. Anyway, thank you. At least it worked!
