OptiStruct will continue to support the old input format from version 3.5. The new optimization capabilities will not be available if the old format is used for the set up of the optimization problem, that is, if matfrac, mini, maxi, ubcon or lbcon are present. This section is intended to be used for the purpose of debugging or re-running older decks.
Setting up an optimization was simpler in OptiStruct 3.5, but it was also very limited. Starting with OptiStruct 5.0, a lot more flexibility has been added to the way objectives and constraints are set up, but the problem setup is more complex.
