Pitching and Plunging Oscillation with Broadband forcing

I want to know if it is possible to define in the UDF for the pluging and pitching of an airfoil a random function instead of sinusiod.
instead of sin cos, I want to use rand function, but how I dont know? Any help?
My 2nd question : I always have the problem of negative voulme cells when I use the dynamic mesh feature.
For the dynamic zone, I define only the airfoil and it is rigid body motion.
I choose layer, then both smoothing and remeshing but no success.
After some iterations I get negative volume cells.
Thanks a lot
