Petsc error when trying to run dafoam v3.1.0

[uttamcadambi07]

Hi,

So I was running dafoam v3.1.0 from an external harddisk through a virtual machine. Using ubuntu v20.04. The host OS was Windows 10.

We recently upgraded to Windows 11. I unplugged the docking station and replugged it back after Windows 11 was installed and launched Ubuntu 20.04 from the harddisk connected to the docking station.

I was able to run Openfoam correctly. I am also able to compile dafoam. But, when i try to run a dafoam case, this is what i get

Now I was obviously inclined to reinstall petsc (after reconfiguring it) and the error still persisted.

I checked OpenFOAM-v1812/platforms/linux64ICCOpt/lib/* and noticed that the shared object files were compiled much earlier. Same with OpenFOAM ADR and ADF

What could be causing this error? Do I have to recompile everything because of change in hardware?

I suspect this is related to the compatibility of file storage systems. May be you need to reinstall everything for Win 11.
