This error message suggest the problem with your model. Check connectivity between your elements, boundary conditions, and make sure not to have "hanging" nodes.

I have checked upto my level best, but not able to find the mistake. please have a look on the program that I have posted earlier and tell me about my problem.

Dear Vesna,

Will you please whether I used the SimpleContact3D element in correct way or not because that is used for the connectivity. Please reply soon
