At least one contact pair has no elements in it.  This may be due to mesh defeaturing.  Please modify defeaturing settings which are accessible on the Mesh object.  Alternatively, set the variable "contactAllowEmpty" to 1 in order to allow the solution to proceed with a warning which can be used to identify the offending pair(s).

Under Mesh Details, set Mesh Defeaturing Off.  If you still get this error, try to set the variable as described. If you struggle with that, come back with a request for more detailed instructions.

 After these modification mesh isn't generating. mesh command just going on no response at all.

The maximum contact stiffness is too big. This may affect the accuracy of the results. You may need to scale the force unit in the model.

Insufficient memory was available for the solver engine to obtain a solution.  Try simplifying the model to reduce problem size. 

[peteroznewman]

You have too many nodes and elements for the size of the RAM installed in your computer. Reduce the number of nodes and elements by at least 50%. If you get the insufficient memory error again, reduce the nodes and elements by another 50% and restart your computer before you Solve.

What units did you use when you did the solve?  If it was m, try changing to mm before you Solve.

how can i reduce element size i don't get it?
