Hi Foamers,

I am getting the following error from one of the computers I am doing simulations on:

The same simulation runs fine on other computers.

OF: OpenFOAM 1812
Solver: chtMultiRegionSimpleFoam
Mesh: Imported from SALOME (checked the mesh and it runs fine on other computers)
Mode: Tried both running in parallel and normal, same error
Comment: Sometimes the error happened earlier (even before the first iteration)
OS: WSL2 (Ubuntu 18.04)

Tried importing WSL configuration from another PC but the error remained. Seems something on the host Windows is causing this.

Any ideas?

Hi mm66!

Did you solve your problem?

I have the same error with my simulation on ubuntu 18.04 wsl.

Hi,


This error message is rather general. For my case it turned out to be the modification I made to the page file size. I reduced the size (due to low space) and the error message appeared. Then I changed the page file size to the initial value and voila it ran perfectly...


Hope this helps
