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.
Before you begin, copy the file(s) used in this tutorial to your

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 HyperMesh version 13.0.210 or later.
