Hello all

Is there a way for me to see how long it's taken to run sims? After executing the command

mpirun -np 16 interFoam -parallel

the time pops up in the terminal. But if I close the terminal I'll lose the total runtime. Is there a way to see this, like in a printed file?

You could redirect the output to a file like so:


Linux:

mpirun -np 16 interFoam -parallel > log.txt &

Windows:

START /B mpirun -np 16 interFoam -parallel > log.txt

Explanation:

• > log.txt redirects to a text file
• [...] & (Linux) and START /B [...] (Windows) run the program in the background

Hope this helps

Thanks so much for the reply! Quick question: if a run this command, then exit the simulation and then resume, will the time be total elapsed or just the time since I re-executed the simulation

The time in the logs will always be for each separate call of the solver. The symbol > will overwrite the log file after each call. If you want to append to the log file instead, use >>. Alternatively, you can just change the name of the log each run (e.g., command > log1, command > log2).
