I want to integrate a part of fluid zone to investigate some variables summation. for example, production of K or dissipation rate. who can give me some advice or recommend materials?

thanks in advance.

I think you can use this method: REPORT=>VOLUME INTEGRALS

hope be useful.

hi,svh, REPORT=>VOLUME INTEGRALS can only be used for the whole flow domain, My interest is about integrating one part volume among the whole flow domain. The question is how to specify a concerned part domain.

thank you.

To have a part of your fluid as a different volume , it must be defined in gambit (while creating geometry),I don't know if it is possible to define it now? hope be successful.
