can anybody tell me what is wrong in this udf code i have written for a wind turbine analysis.
prop[SDOF_MASS]= 0.122; /*mass of body*/
prop[SDOF_IZZ]= -0.0004307; /*inertia moment of body in z_direction*/
prop[SDOF_ZERO_ROT_Z]= FALSE; /*allow rotate in z_direction*/

What is the error that you are getting?

thank you, sir for your replay, actually i want to rotate a 3d fan in z axis but after uploading this code i am getting a message 6dof cant compute angular acceleration, and one more message i am getting ( no motion is detected in current time step), can you please tell me where i did wrong...
sir , should i add moment of inertia in all direction in sdof code .....

If you just want rotation have you looked at the sliding mesh approach?
October 17, 2020 at 9:56 amamir2020Subscriberthe rotation is for wind driven n
