Libmesh terminating: ERROR: cannot locate specified file

[LeonDong1998]

Hello everyone!
I recently encountered a strange problem while coupling MOOSE and OpenMC using Cardinal. The mesh I generated using Cubit works fine in a standalone MOOSE calculation, but when running a coupled calculation, I get the following error:

Libmesh terminating: ERROR: cannot locate specified file: 1.e.1.0

My mesh is named 1.e, and it seems libmesh isn't recognizing it.

Thanks in advance!

Hello

Looks like it's looking for a split file rather than just the file.
Are you using the pre-split capability?

Thank you very much! I've found the problem! I accidentally used a purely numeric file name. The MOOSE operation worked fine, but the problem occurred when coupled with OpenMC. Changing the name of the .e file fixed it.
