Hi,
My model is a rigid body container (a thin wall) with deformable body inside. Running explicit, I frequenty have the overclosure problem. Abaqus tried to adjust the nodes cooridinates on the slave surface (the deformable body surface), but still there were unresolved initial overclosure "stored as offsets". Could someone elaborate a little bit on this? I have read the manual several times, but couldn't get a good sense of it. BTW -- the rigid body and deformable body surfaces are geometrically coincide. So the overclosure problem should be due only to discreet meshing.
In addition, it seems that during the analysis, a few deformable body nodes went ouside the container wall, giving a suprious result. This should not happen in real world, how can I prevent that happening in Abaqus? I am using general contact algorithm. Thanks.
