Hello： I ran my example on Linux this time, but still reported the following error. I tried other examples and reported the same error. But I ran your SVD decomposition code for the flow past a cylinder and it worked perfectly. So I checked the blockMesh file of the cylinder flow around the dataset you provided. The grid settings are as follows. Is this error related to this setting?

The error happens when parsing the mesh data. Are you sure a valid mesh was created (e.g., can you open and visualize the mesh in ParaView)? If so, there seems to be something wrong with the file header of constant/polyMesh/owner. Two options:

• pre-compute the cell centers and volumes using

  postProcess -func "writeCellCentres" -constant -time none
  postProcess -func "writeCellVolumes" -constant -time none

• zip the clean test case and attach to this issue Best, Andre

SandiaD_LTS1.zip This is a case in the openfoam/tutorials/collaboration/reatingFoam/RAS directory. I looked at the polymesh/owner file and it seems that there is indeed a problem, but I don't know how to solve it.The simulation time is 5000s. Due to limitations in the size of uploaded files, I deleted some files with time steps.And during the calculation process, the following errors may occur. Is this related to the above problem?

Thanks for uploading the case files. The problem is with your OpenFOAM version, which is a special compilation by some commercial company:

As mentioned before, flowTorch only supports the ESI OpenFOAM version, which is the one available at www.openfoam.com Best regards, Andre

This version doesn't work, does it?

[AndreWeiner]

No, that's openfoam.org.

[JOEJOEJOE1231231231231]

Thank you !

[JOEJOEJOE1231231231231]

Running code that pre calculates the unit center and volume can effectively solve this problem, and doing so can run flowtorch on the org version of Openfoam

Alright, good to know. Thanks for the feedback. Best, Andre
