GMO suddenly can not move!

yongticle · January 31, 2018, 05:07

Hello,

I have a problem about GMO! I use the nested meshing block to simulate eight components with GMO (size: 13*0.7*3.7cm, and mass density =3000 in SI) in coupled motion and fixed x-axis rotation. However, there are two components can't move.
i am wondering if the grid size (0.77*0.61*0.8cm) can affect GMO to move?
Because those components all moved when i set the grid size (0.5*0.25*0.5cm) in first time without nested meshing block.

Thanks.

Please send both the prepins:

1. without nested block
2. with nested block
