OpenFoam parallel running log issue

clktp · January 19, 2016, 08:37

Hello,

When I run something parallel, there isn't anything written in log file, however, when it's serial there isn't any problem.

I'm using this command.
mpirun -np 2 simpleFoam -parallel > log &

I have the log file only after it's completed. It's really annoying, because I can't check the residuals or how much time I need.

I checked the forum a bit, but I couldn't find any solution or see anybody had this problem.

Regards,

Hi,

Code:

mpirun -np 2 simpleFoam -parallel | tee log.simpleFoam

works well for me, and gives you the terminal output + the log file.
