nRead the error message and do what it says to do...check your environment for insufficient supports, or excessive loads or wrong material properties.nDoes this model have nonlinear contact?n

yes , It is the nonlinear .nI try many trier but I dont know wha i solve this problem ,please can you check the model and tell me what shoud i do ,please .nhttps://www.dropbox.com/s/ok1d7162srocu5z/isolator%204.mechdat?dl=0n

nWhen things don't work, a good strategy is to simplify. What is the most important feature in this model? What questions do you want the model to answer?n

[ahlamosama]

all parts are important for me , I solve this problem to calculate the maximum tenstion and compression by added many forces , i would solve nonlinear .ncan you help me to find the problem ?nn

[ahlamosama]

can you help me mr nIt is the most important project for me . please ,n

nMy suggestion is to have a simpler model and get that running first, then add more parts, check that is running, and continue this process until all the parts are included.nIt seems to me that the most important feature is the spring in the middle, the cup around it at each end and the bottom and top plates. Get a model running with just those five parts.nAn even simpler model is to have just the spring and no contact. Hold one end of the wire fixed and put a remote displacement on the other end of the wire. That remote displacement should set all DOF to zero except for the axial displacement that will compress the spring. That is guaranteed to run and will give you the first result for the forces that this spring can develop. All the other parts will only modify that value slightly.n
