Hello, I was trying to run a simulation with a mesh generated from Ansys Workbench Meshing.
When I ran it, the error came up as

"*** glibc detected *** /work/e01/e01/iorishx/build/cs-4.0.1/libexec/code_saturne/cs_solver: realloc(): invalid old size: 0x0000000001f7bef0 ***

I have attached the error file and listing file. Can anyone help please? Is it boundary conditions setting problem? I do appreciate it!!

Hello,

The code should exit more cleanly, so you may have encountered a minor bug, but by your "listing" file, you already have joining issues.

The issue is probably more a mesh quality issue than a mesh format issue, but you need to check in more detail.

So the first recommendation is to visualize the mesh joining (used for periodicity also), and possibly check the theory manual section relative to mesh joining (to check in more detail what configurations to avoid, if the error is not clear enough), so as to see what is wrong.
