Define an equation for the inlet velocity profile
Dear CFX guys; I am trying to define an equation for the 2D inlet velocity profile. I am defined two equations for the vertical coordinate where I'd like to divide the vertical coordinate to two stages, since i have for each segment different equation.
I wrote the equation using the CEL function but my problem is how to tell the CFX function to use equation 1 for the 1st segment and equation 2 for the other. for instance from 0<y<1 i need it to read equation 1. and from 1<y<10 to read equation 2.

Use step function. The step function is used as an example in the documentation to set the initial pressure in a water/air with sealevel case. Check that out.

I have the same problem and tried to use the profile data, however till now I've not been able to set it correctly.

I solved my problem in different way, i generate two surfaces for the inlet and i defined an equation for each surface. Hope that will help.
