rigid body force
hi.
i creat a rigid body in cfx and i want to give it a special harmonic froce in rigid body's ceter of mass. the problem is that my rigid body moves and i dont know how to set this force that always be in the center of mass. :mad: (my problem is transient and the rigid body should move with this force.) thanks a lot |
Correct me if i am wrong but as it is a rigid body defined with its mass & mass moments of inertia so any force applied (assuming you're talking about external force in rigid body definition) would always be acting at the center of mass... have you tried anything yet that led you to your question? Any images or details would be helpful..

thank u a lot.
u solved my question i have 2 another questions. 1-does the external force be continuous? 2-i choose a new coordinate for the rigid body. in the initial condition which coordinate will be considered? new coordinate or the main coordinate? |

Would give my best shot at trying to comprehend...
1) The external force is continuous 2) It would consider the same coordinate system as selected in the Basic Settings tab |
