Hello Foamers,

In OpenFoam 2.2.2, I'm trying to sample surfaces at the end of my simulations. I didn't managed to setup the sampleDict in 2.2.2 version to extract variables on a surfaces so I'm trying another approach: I use the cuttingPlane function in my controlDict (see below).

However, I need to extract both solved variables (like U) and unsolved variables which can be calculated through post-processing commands (like magU). If I write both variables in the cuttingPlane function, only U is printed. Do you know how to have a variable such as magU exported from cuttingPlane function? Or how the sampleDict should be written in OF2.2.2 in order to extract a surface?

Thanks for your help!
Regards,
Eloïse
