How to apply gravity load on COG? should i create Rigids for whole body and apply gravity load on that?? but my model already as rigids for few parts, wont that produce errors?
Hi,
For gravity load select all the nodes in the model and apply. As your model already has rigids and making again those in global rigid body can end up in error.
It seems you want to go for only free fall with body in rigid state. You can go for making global rigid body and apply gravity to it and make all RBODY OFF in engine file and RBODY ON for the global rigid body.
im doing for bus roll over, as per my requirement im said to give gravity load on COG and ini.velocity on bus body. As my model already contains rigid, i cant create rigid to create Global COG. if i do so i'll get errors only.
You will not get errors if you can switch off all rigid bodies except global rigid body during free fall with first engine file and then reverse in second engine file.
Hi Guru,
As Gopal mentioned, you can run with /RBODY/ON and /RBODY/OFF options.
You can go through Example 12 - Jumping Bicycle in our Help Menu where similar cards are used.

can you please upload the model in block 120 format?
Please check the model file.
