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 :
- Pressure - Overclosure : "Hard" contact
- Constraint enforcement method : Default
Allow separation after contact : yes
- 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.
