Right mouse button on the active solution and select edit.  Under the general section toggle on (check box)  Element Iterative Solver.
         

Element iterative solver
The element iterative solver is supported by Simcenter Nastran in SOL 101, and 401 analyses only. You can include contact conditions in SOL 101 analyses with the iterative solver. With the element iterative solver, the software works entirely from the element matrices. Use of the element iterative solver yields typical run time improvements of 4x to 6x compared to the global iterative solver. Additionally, the element iterative solver uses significantly less disk space. These performance gains are most noticeable with models composed of mostly solid elements.
There are several restrictions for using the element iterative solver. For example, the element iterative solver does not support superelements or inertia relief. For a complete list of these restrictions, see remark 2 for the ITER entry in the Simcenter Nastran Quick Reference Guide.
For more information, see Iterative Solutions in the Simcenter Nastran Numerical Methods User's Guide and Contact Conditions with the Element Iterative Solver.
