3D visualization support for parameters in a disv grid in MF6

[porterma]

I have been searching for an export option so that I can visualize hydrogeologic properties such as K in 3D. I was thinking there would be a vtk option, but I can't seem to find it for MF6. Looking at the code for the Vtk class appears to only support a structured grid and applies to the .dis package only. Am I missing something in this class? I have my unstructured grid loaded in Paraview using the .vtu file provided by the Gridgen module. It appears that flopy.export.utils.package_export() only supports shapefile files and netcdf. Is this correct? I tried
npf = flopy.mf6.ModflowGwfnpf(mdl, save_specific_discharge=True, icelltype=[1, 1, 1], k=hk_qt, k33=vk_qt)
npf.export('_netcdf/npf.nc')
and
flopy.export.utils.package_export('_netcdf/npf.nc', npf)
In both cases I received the same error: Exception: Grid type vertex not supported. So it appears the netcdf export option does not support unstructured grids.

Are there any 3D export options to visualize hydrogeologic parameters?

We are presently retooling the export functionality to support vtk export for all of our grid types, including unstructured grids. We have a prototype for this on a developer's branch, but it has not been folded back into the flopy develop branch. We are probably looking at a month or two to get it rolled in. We are close, but I'm afraid you'll have to just stay tuned for the moment. Sorry.

No worries! I look froward to the updated export features. In the meantime, I I have some ideas I can test on updating the existing .vtu file with the scalar K data. Thanks!
