i am getting very large displacement, when I solve in Radioss or Opristruct (value ranging e9)

When The same problem i solved in Nastran Solver, without modifying the mesh and other parameters the diplacement value is just 1.5 mm

Further i need to optimize the model so it is very necessary to solve in optistruct correctly.

Please help.

    It sounds like your model is not constrained enough in Radioss. Are there any warning messages in the Radioss model?
