Our review
Pros
  • Free interactive 2D and 3D topology optimization
  • Multiple load cases, gravity, and passive solid or void elements
  • MATLAB, Python, PETSc, COMSOL, and Grasshopper integrations
  • Covers topology, shape, sizing, and bead optimization methods
  • Handles manufacturing conditions, including casting restrictions
  • Connects Abaqus/CAE, cloud SIMULIA access, and durability workflows
Cons
  • 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
  • Pricing requires contacting sales
  • Its workflow is centered on engineering simulation and optimization
  • The broad feature set may exceed narrow design needs
