analyses across statics and dynamics, vibrations, acoustics, fatigue, heat transfer, and multiphysics disciplines.
Composite materials have become popular in the application of aircraft structures. The need for innovative designs
has posed a great challenge. In this tutorial you will perform an optimization-driven design approach of a composite
aircraft underbelly fairing using OptiStruct.
In this tutorial you will learn how to set up a basic lattice concept-level (Phase 1) optimization using the DTPL card, set up and review the basic options associated with lattice optimization, and set up a basic lattice fine-tuning
(Phase 2) optimization and review the results.

Lattice Optimization in OptiStruct is a two-phase process
to create blended Solid and Lattice structures from concept to the detailed final
design. The first phase performs a concept-level topology optimization to optimally
partition solid, void, and intermediate space and create the lattice elements. The
second phase optimizes the size of each lattice element to determine the final
optimized structure. The completed model can then be manually reinterpreted to fit a
number of different manufacturing operations, including, but not limited to, 3D
printing.
Note: Running Lattice Optimization requires HyperWorks version 13.0.210 or later.
The optimization problem may be stated as:

Control Arm, sectioned into non-design and designable components.
