(OP)
hello ,
I think i have many problems in my model.It's makes me crazy because i think it's an easy problem :s
I'll describe what I did.
I drew the shell part in solidworks, after that i imported it in Abaqus.(I ran the simulation in Solidworks and it works , i have to verify my results in Abaqus)
I have two kinds of problem :
1)Contact problem : Abaqus show me this message Error : "The model has 26 unconnected regions".i tried to impose tie contact but it stills no work.i have made a static analysis and abaqus say me that there are UNCONNECTED REGIONS.
2) Application of the force: " this node set is not active in your model" ..

please help me if you know the answer.

Thank you
