Hi,
im trying to make a projection in a 3d comsol model.
I have a non uniforme chanel and my intention is to get the average tempreture in the y-z cross section and se the average tempreture along the length of the chanel
From what a i could find online it seems this can be done with a general projection but i don't understan how to use it, and i can't find a flull eponetion about it
