Hi again. I wish to use OpenFOAM to calculate velocity magnitudes in the flow field with respect to time however I have only been able to code for the two respective points below to resolve the u, v and w components which I would rather not have to post-process. I think that the magnitudes need to be calculated and then magU used but I haven't seen this explicitly coded elsewhere on some google searches. Any help would be appreciated, if I haven't explained myself clearly enough then let me know!

Thanks.
