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!

Default Is that true about 1e-6?

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
