Hi,
I posted the message below 20 days ago. I have not received a response. If someone has experience with this issue, I would be grateful if you could respond. Thanks.
I am sorry if this matter has already been raised. I performed some cursory checks and could not find a relevant topic related to this.
I have Paraview 5.6.0 and 4.40 installed on a Windows 10 platform. I am trying to visualize transient CFD data from a multiprocessor run using openFoam. I have data for Paraview input prepared as native openFoam (distributed and reconstructed in which the respective folders includes a case.foam file) and VTK files created using the foamToVTK utility.
Paraview 5.6.0 and 4.40 fail to read in the data when I attempt to ‘Apply’ after reading the case .foam file and the ‘Case Type’ is listed as ‘Decomposed Case’. If I reconstruct the data using the appropriate utility in openFoam and then try to read it in to Paraview, there is no problem.
I will note that when I try to read in the ‘Decomposed Case’ using Paraview 4.4.0 on a Windows 7 platform, I do NOT get any error message. The error messages have been attached as a PowerPoint. I hope they come through OK.
Does anyone know why this problem is occurring with decomposed data on Windows 10?
Thank you.

Hello,
Thank you for your response. I will need to set this up with one of the OpenFoam tutorial test cases, as the one I am working with is confidential. However, I would like to know if there is a size limit on what can be uploaded. Please advise.

Yes there is a limit, but you can use an external sharing site if necessary.

Hi,
I’ve loaded some data sets as part of this link a few days ago. Please let me know if you were able to download and reproduce the error. Thank you:

> 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: pitzdaily.tar.gz pitzdaily\_exp.tar.gz - same as 1, except results are written out at very early time steps such that the data folders are express…
