Great difference between ExecutionTime and ClockTime


#1

Hello SimScaler’s

in my Simulation the difference between ExecutionTime and clockTime is around 40%?

ExecutionTime = 664.71 s ClockTime = 1130 s_
End_

i used 1 processor for a mesh with 13k cells and the solver was
rhoCentralFoam.

And which time will be used for calculating the cpu-hours?

Hi @mjosic!

Maybe this link might help you better understand the definition of what core hours are.

Cheers.
