I am new to Abaqus so I have started doing a simpler problem in which a load has been applied on the end of a cantilever beam below which a fixed plate is placed such that deflection of the beam is more than the distance between fixed plate and beam also I have specified interaction as a surface to surface contact with frictionless contact property and hard contact. but during running it shows there are “two unconnected region errors in Abaqus” please help
