Hi,

Thank you for looking into this! I am attaching a few tar archives containing example data from the pitzDaily tutorial of OpenFoam (v1806) exemplifying the issue. The archives contain all the necessary dictionary files to re-run the calculations. I’ve modified controlDict to ensure only two time steps are written out. There are four archives:

1. pitzdaily.tar.gz
2. pitzdaily\_exp.tar.gz - same as 1, except results are written out at very early time steps such that the data folders are expressed in using scientific notation (5e-06/ and 1e-05/).
3. pitzdaily\_par.tar.gz - same as 1, except the calculation is run in parallel using mpi.
4. pitzDaily\_reconstr.tar.gz - same as 3, but results have been reconstructed using foamToVTK.

Except for archive #3, all examples have a VTK folder too. I have read in data using two approaches:  
a) Read in case.foam file in the respective folder. Then Apply.  
b) Read in .vtk group file in the VTK folder of the respective example.

I see error pop-up windows appear when I try to read in the data, depending on whether I utilize approach a) or b) listed above using ParaView 5.6.0 on Windows 7, and ParaView 5.6.0 (and 5.6.1) on Windows 10. I understand from a work colleague that no error pop-up windows appeared when he tried loading the data using a Mac with macOS Mojave (10.14.5) and ParaView 5.6.0. The results I obtained are listed below:

Folder Outcome Case.foam Outcome VTK  
pitzDaily Error after data Apply It works!  
pitzDaily\_par Error after data Apply N/A  
pitzDaily\_reconstr Error after data Apply It works!  
pitzDaily\_exp Error after data Apply Error after data Apply

Please note how there is also an error with the VTK data input when the results are written out to folders in expoential format (pitzDaily\_exp).

Here are the links to the archives.

Many thanks for your help.
