Help on nonlinear simulation

Hi I am new to solid works and trying to get around the simulation.

I am trying to find out the amount of load require to separate the 2 piece.

Under simulation I chose non linear - dynamic 2d - plane 2mm.

Fixeture

Contacts.

I am not sure what to add so i did as below.

Deleted the component contact

And i mesh and run

and keep on getting this error.

Please tell me if my steps is correct?
