UDF for inlet velocity profile
I'm using a UDF for a velocity profile to define the atmospheric boundary layer in a 2D problem. I've used the attached c code as explained in the user manual, apparently it's interpreted properly but results don't show any influence on the profile, it appears to be just a uniform velocity at the inlet (see attached picture for 5s).
1) Which can be the problem? Is there something wrong in the code?
2) What will happen if I modify the ymax coord in the code so it's higher than the domains's ymax?
3) Also I would like to use a profile for the turbulence intensity (TI), but Fluent only allows me to use it for k and epsilon. Is there a way to use TI and Turbulent Length Scale (TLS) instead of applying the formulae for (TI,TLS)(k,epsilon).
4) I will need to apply the same profile to a 3D case. It will be exactly the same in the x-y plane and constant in the z-direction. Can I use directly the same code? If not, what do I have to modify?
Thanks you all!
