Plato
Albuquerque, New Mexico, USA
What it is
Plato is Linux software for topology optimization, helping designers develop shapes that meet functional requirements. Its gradient-based methods address topology and shape design using adjoint methods. Documented objectives include increasing stiffness or heat flow and reducing stress. Plato coordinates work across geometry, meshing, and physics simulation software, and includes the open-source physics code Plato Analyze. It can also be used with a growing list of internal Sandia physics codes. Research areas described for Plato include multi-material and uncertainty-aware structural optimization, level-set methods, and a massively parallel kernel filter. The application uses a command line; a graphical interface is being developed for targeted applications. Installation requires a license, and licensed users are directed to contact the Plato team for an install package. The Open source version is free, with a limited set of objectives and constraints. A no-fee Government Use license is available for qualifying U.S. government agencies and contractors working under contract to the government or an agency.
For and against
For
- Includes the open-source Plato Analyze physics code
- Supports objectives for stiffness, heat flow, and stress
- Coordinates geometry, meshing, and simulation workflows
- Open source version is free
Against
- Linux platform only
- Command-line application; graphical interface is still in development
- Installation package requires a license
- Open source version has limited objectives and constraints
The verdict
Plato brings optimization methods and simulation workflows together for Linux-based design work. Its command-line interface and license requirement for installation are important considerations.
Who it suits
Plato suits designers working on topology or shape optimization problems, including those considering additive processes. Its Linux command-line interface is suited to users comfortable working without a graphical interface.
