Default UDF-Boundary Profiles

Dear Fluent-Users,

I have to use UDFs to define turbulent boundary conditions at the velocity-inlet of my domain. The domain is nearly a quader, but the bottom surface is of complex geometry (mountain scape). So I have to define my BCs at the inlet not as function of absolute altitude(z-coordinate) but as function of relative altitude above the ground. Do You have any idea, how I can get the values of the relative altitude???

Thanks
