Define sections
 

Dear all,

I would like to perform integrations and averages on a section of my 3D domain, considering only a subset of the cells cut by the section plane (e.g., I have two coaxial pipes, and I would like to perform the integration only on the inner one and not on the annulus).

Which is the best way to do this in StarCD?

Thank you very much in advance.

Regards,

Ale
