This seems to be due to an incorrect handling of reducers, fixed in commit 5de8c9 .

Best regards,

Hi everyone,

I have some new findings regarding my simulation.

I discovered that when I run the calculation using a single core (serial) , the "infinite virtual box" error does not occur. However, as soon as I switch to multi-core parallel computation (MPI) , the virtual box coordinates become ...

Issue with Infinite SEM Virtual Box Dimensions (coo_min = -1e30) on Annular Inlet [V9.1]

Hello Code_Saturne community,

I am currently running an LES simulation (WALE model) of a rotating disk cavity with axial through-flow on a cluster (using MPI). I am trying to impose synthetic turbulence at the inlet using the Synthetic Eddy Method (SEM).

Case Setup :
Version: Code_Saturne V9.1 ...
