Helo!
I use a very simple udf to define rigid body motion as follows: #include "udf.h" DEFINE_CG_MOTION(flutter, dt, vel, omega, time, dtime); { omega[2] = 0.1*cos(time); } It works, the body moves as desired, but if i use "omega[2] = 0.1*cos(10*time);" or i multiply the "time" with anything, the Fluent rotates the body not with the defined aplitude, something goes wrong... Can anybody help me? Thanks |
