Dear Felipe Suarez,

In the COMSOL multiphysics user guide you can find a better explanation of how to use the general projection operator. You can find it at page 348:

I hope this will help,

Hi Ciro, thanks for answering

I saw this guide, but i can't understand how to make it work in my case. I don't know if i have exprese it clearly

I have a 3 dimensional gemetry and i want to get the integration of tempreture in Y and Z for every X

Can you explain how to do this? is General projection what i need?

Check the youtube, of the CFD sites, better to ask some colleagues these is they can help.

Effectively youtube can give you answer its is not very difficult to do, good luck
