Summary

Plato is a Linux command-line platform for topology optimization, helping designers develop designs that meet functional requirements. It uses adjoint methods for gradient-based optimization of topology and shape. Documented objectives include maximizing stiffness or heat flow and minimizing stress. Plato coordinates workflows across software for geometry, meshing, and physics simulation, and includes the open-source physics code Plato Analyze. It can also work with a growing list of internal Sandia physics codes. Research features described for the platform include multi-material and uncertainty-aware structural topology optimization, level-set methods, and a massively parallel kernel filter. A graphical interface is being developed for targeted applications. A license is required to obtain an installation package, and licensed users are directed to contact the Plato team. The open-source version is 0.00 USD per free, with a limited set of objectives and constraints. A no-fee Government Use license is listed for U.S. government agencies and contractors working under contract to the government or an agency.

Who it is for

Plato suits designers and researchers working on topology or shape optimization who can use a Linux command-line application. The listed Government Use license is intended for eligible U.S. government agencies and contractors.

What is good
