how do i rectify the singularity error.is it got to do somethign with the boundary condition?

As you indicate that it might have something to do with boundary conditions, is your model undersconstrained? That is, are the rigid body modes present?
One simple way of finding out is to run an eigenfrequency analysis. If there are any modes with f=0 Hz the graphics might indicate what your problem is. Also, just a simple tip. Have you checked for coincident nodes?
For more ideas I/"we" would probably need more information what kind of sigularity problem you have?
Good Luck

It is most likely that you do not have all rigid body modes constrained. Are you running a static stress analysis?
