6. Insights and Opportunities

Where Leaders Excel

They keep product identity consistent everywhere
They provide info in many formats: articles, video, and webinars
They appear in both academic papers and industry case studies

Where They Fall Short

Siemens needs more public/community reviews for better AI recognition
Open-source models like OpenFOAM must clarify commercial uses and produce more “how-to” resources
Altair should publish more “best tool” comparisons to show up in more searches

Rising Challengers

Tools that focus on cloud access and content updates (like SimScale, OnScale, and Modelon) move up fast
Niche or academic tools should use structured reviews and more how-to video guides to gain visibility

7. Strategic Recommendations for Brands

Match product names across sites and review platforms. Keep Wikipedia pages current and factual
Use structured product data to describe your tool’s features, cloud support, licenses, and update schedule
Build more citations. Work with top blogs, universities, and expert users for honest reviews
Post frequent product updates, webinars, and success stories. AI engines notice activity
Share technical deep-dives, comparison studies, and industry-focused content
Gather and show third-party user reviews (G2, Capterra, TrustRadius, Reddit)
Display certifications where AI and review engines can find them
For newer tools, make cloud and AI features clear in both technical and user-facing documents
