Hi everyone,

I ran two simulations of the same geometry, one with a porous patch in one area of the section and one with no patch. The results are in the attachments.

Could anyone give me hints as to how to get a similar display, but showing the relative velocity difference between the two (so to say, to substract one result from the other)?

I'd be greatful for any hints.

Hi Nick,

I am not sure whether foamCalc can handle two different cases, probably not out of the box...

You could always rename one of the fields and copy it over to the other case. Then use foamCalc or directly paraView's calculator filter.

Best,

Pablo
