Nonlinear Static Analysis with large displacement is conducted on this piston assembly,
where pretension force is applied on both the sides of the piston bolts (Figure 1).

Results
Using the conversion tool, you will be able to convert this Abaqus FE model successfully and then the displacements and stress
results should match with Abaqus closely (Figure 2).Figure 2. Stress and Displacement Contour in OptiStruct
