aero_cfd is on a distinguished road
Hi,

I have a profile shape that I would like to scale during the simulation and apply it to a pressure inlet.

I have done something similar with define_profile but using a parabolic shape as it is shown in the user guide, but what I want is to do the same but based on a shape that I already have.

Is there a way to that in the UDF?

Thanks!

find the equation to represent shape you need, use it in UDF instead of parabolic equation from example
