OptiStruct is a proven, modern structural solver with comprehensive, accurate and scalable solutions for linear and nonlinear
analyses across statics and dynamics, vibrations, acoustics, fatigue, heat transfer, and multiphysics disciplines.
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.
The OptiStruct Example Guide is a collection of solved examples for various solution sequences and optimization types and provides
you with examples of the real-world applications and capabilities of OptiStruct.
