Hi,

I generated some NetCDF files using FloPy ([flopy3\_export.ipynb](https://github.com/modflowpy/flopy/blob/develop/examples/Notebooks/flopy3_export.ipynb)) and tried to import and view these in ParaView, but I get an ‘Incorrect Dimensionality’ error for every single file NetCDF (.nc) file.

Any ideas what might be causing this error or any tips on how I might be able to troubleshoot it?

Thanks!

Hi @datathing ,

Today I stumbled over your post, since i had the same Error for my netcdf-data (Paraview 5.6.0)

What helped on my side, was to use the filter `ImageDatatoPointSet`, and after that I can visualize my data correctly.

Unfortunately, I cannot exactly locate, where/why the error occurs, since I tried to manipulate the data with certain attributes (axis, cordinates, featureType,…) but the error persits.

I also attached a short example on how I created the data ([sample\_netcdf\_1D.py](https://discourse.paraview.org/uploads/short-url/u5NKW9vaGB7OgFbV40sdWmIdof8.py) (697 Bytes)) and the data itself ([two\_2.nc](https://discourse.paraview.org/uploads/short-url/dLdMQqVnSLyAAulVdphyi5VkZti.nc) (664 Bytes)) for others to see and test, or maybe give a hint on what is wrong/missing in the dataset.

So far, I have only worked with netCDF containing planes or volumes. But I have noticed that ParaView requires a specific order of the data. In my case I need to apply permutations for a correct visualization. In your case it may be that the 1D case is not supported…?
