Hi all,
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 Selim |
