Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
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
  • Combines sensitivity analysis, optimization, and reliability analysis.
  • Automates simulation workflows across Ansys and third-party CAE/CAD tools.
  • Publishes, manages, and monitors projects through a web service.
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
  • Its focus is simulation-led exploration, not direct generative geometry creation.
  • Pricing is handled through sales rather than a public price list.
  • Support channels listed include documentation only.
