Hello,

What does qwf_u command mean? I want to calculate the convection heat transfer coefficient h. After that, the number of Nusselt.

Thanks for helping me.

Hi

What about checking the CFD documentation (p231 v5.3) "wall function heat flux" the _u probably stand for the u component, check it out in the Equation View with the hint of Jeff.

When I have a doubt I run an index search on the COMSOL pdf docs, therein you find everything, but there are so many formulas and variables ;) For the rest the Equation view gives you the complements

Good luck

Hi,

if you do not want to help, I beg you not to respond. I already looked but I still did not understand. I do not have experience with the computational package.

A hug.

I already did it but I still have doubts.

Grateful.
