Strengths and trade-offs
Ansys Discovery — where it wins
- Real-time structural, fluid, and solid-fluid thermal analysis
- Topology optimization includes manufacturing constraints
- Transfers geometry and physics to other Ansys tools
Where it doesn't
- Commercial pricing requires contacting sales
- Desktop support is limited to Windows
- The free trial lasts 30 days; there is no free plan
TopOpt — where it wins
- Free interactive 2D and 3D topology optimization
- Multiple load cases, gravity, and passive solid or void elements
- MATLAB, Python, PETSc, COMSOL, and Grasshopper integrations
Where it doesn't
- 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
