SU2 parallel run on Windows: console output appears in large blocks instead of step by step #2808

Description

Hello everyone,

I am running SU2 in parallel on Windows using MPI. The case can run, but I noticed a strange behavior in the console output.

When I run SU2 in serial mode:

SU2_CFD.exe config.cfg

the screen output appears normally, step by step.

However, when I run SU2 in parallel mode:

mpiexec -n 4 SU2_CFD.exe config.cfg

the screen does not update continuously. It looks like the program is frozen for some time, and then suddenly many lines of iteration information appear at once.
Has anyone encountered the same problem? Any suggestions would be appreciated.

Thank you!
