Hi all

I created a DFBI Embedded Rotation with freely pitching about y-axis and given the mass and Moment of Inertia. When i click Run Star-CCM+ throw an error "BodyHandle: no Body defined!"

Please help me here.
Thanks in Advance

Cheers

Hi Mohammed,

To create a DFBI motion in STAR-CCM+, you need to follow these steps:

1. Create the motion under Tools > Motions, as you did.
2. Apply the motion to a certain region, under "Region 1" > Physics Values > Motion Specification
3. Create the 6-DOF body under DFBI > 6-DOF Bodies
4. Select the boundaries that encompass the surfaces of the body, under DFBI > 6-DOF Bodies > "Body 1" > Parts
5. Specify mass, moment of inertia, etc. of the 6-DOF body

I suspect you might have missed step #4 in the above list.

There are a couple of good tutorials in STAR-CCM+ documentation where the above workflow is demonstrated, particularly the "boat in head waves" and the "lifeboat release" tutorials. You might want to check them out.

Regards,
MI
