Hi all,

I'm working on a 2D model where I impose a little vertical displacement to the half-sphere into the parallelepiped.

I declared a node-to-surface contact with these properties :

  • Normal behavior :

- Pressure - Overclosure : "Hard" contact

- Constraint enforcement method : Default

Allow separation after contact : yes

  • Tangential behavior:

- Friction formulation : Penalty

- Directionality : isotropic

- Friction coeff : 0.5 (I don't use slip rate, contact-pressure, temperature and field variables)

When I run the job there is this warning : "There are 2 unconnected regions in the model."

The job is completed successfully and the results seem to be good but later I want to make the half-sphere slide on the parallelepiped and maybe it would be problematic.

Thanks in advance for your answers.
