6dof: low moment of inerti a
 
Hi!
I want to simulate the leaflets rotation in a bileaflet mechanical heart valve using the 6dof.
The moments of inertia are about 2e-8 kg*m2 and the mass is 3,86e-4 kg.

Because of the low moments of inertia fluent can't compute angular acceleration.

I know that the 6dof variables can only process solid body moments of inertia>=1e-06.

How can I solve my problem?

Please help me!

Is that true about 1e-6?
 
Really? Can you told me where in the help file of ansys can find this?

HIE EVERYONE....

Can anyone help out with problem of overset mesh with
DFBI rotation and translation for a propeller with a shaft in star ccm+

Is this model is good to apply to the propeller (rotate along y-axis and translate along x axis ) and to translate the shaft in x-axis.

And need to apply the 6DOF for the complete body
