Integrating magU over whole domain

CTR · July 25, 2014, 06:46

Hi all,

I am pretty new to OpenFOAM and I don't know all the postprocessing tool available. I want to take the integral of velocity magnitude throughout the domain for every time step. I have used foamCalc to get magU but how do I do the integration? is there a utility for that? If not can anyone suggest a good way of doing this post processing? I tried looking in the user guide but nothing seemed right for this task. Thanks for your time.

Regards
Charles

well if you want to sum the magnitude of velocity

, then you can simply use swak4Foam which is a third party written in python come with OpenFOAM
