Extract a vertical profile in volScalarField

begou · June 3, 2009, 12:35

I'm quite new with OpenFOAM and I have to help a student who want to extract vertical profiles in his calculation domain.
I've find all that I need in volScalarField class (mesh and scalar values): I can print the cell center position and scalar value for each cell.
But I do not understand how to find (select) the cells along a vertical axis located at the (X,Y) position where I wont to extract the vertical profile.

I think this is a common thing when working with openFoam. Any help or starting point to read is welcome.

Thanks

Patrick

Hi Patrick

Look into the "sample" utility. You will be able to find the required sampleDict in:

~/OpenFOAM/OpenFOAM-1.5.x/applications/utilities/postProcessing/sampling/sample

Reading the above should be quite self-explanatory.

Best regards,

Niels
