UDF for heat transfer coeff..
I want to give convection boundary condition (heat transfer coeff and temp) on a 3d olbique surface. the heat transfer coeff and temp values are obtained at certain intervals along the plane experimentally. To apply these values which are function of x, y and z, is it possible to apply using define_profile macro?? If so, how the equation cn be written? I hope you understand my doubt!
thanks and regards ravi 
Re: UDF for heat transfer coeff..
If the case is an unsteady case , you could use the execute_at_end macro which executes at the end of time step and you could update the Boundary condition this. Let me know if you need more on this

Its a steady case only. but the problem is its not a function of single coordinate but of all three coordinates x,y,z.
