Pros	Distributed-memory HPC execution for large optimization workflows Supports multi-material, lattice, and metamaterial design research Connects with Sierra, Plato Analyze, Engineering Sketch Pad, and CUBIT	Free interactive 2D and 3D topology optimization Multiple load cases, gravity, and passive solid or void elements MATLAB, Python, PETSc, COMSOL, and Grasshopper integrations
Cons	Linux and self-hosted deployment limit platform flexibility Open-source objectives and constraints are limited Command-line delivery may require engineering and research expertise	More a collection of apps and codes than a conventional SaaS product Manufacturing workflow coverage is narrower than its optimization scope Advanced workflows may require MATLAB, Python, C/C++, or research codes
Our verdict	Plato is Sandia National Laboratories’ optimization-based design software for engineers and researchers working with physics-driven design problems. It generates topology- and shape-optimized designs by connecting mathematical optimization… Read the review →	TopOpt is a free collection of topology-optimization applications, research codes, and frameworks from DTU Mechanical Engineering and DTU Compute.
