dhwaniPRO implements ISO 9613-2:2024 across all editions, with CNOSSOS-EU available in Vector and Delta. Published verification comparisons document numerical differences against reference cases and explain the scope and limitations of those comparisons.
Numerical verification is distinct from independent certification or guaranteed real-world prediction accuracy.
Compare modelling capabilities, review technical requirements and check published licensing terms before purchasing.
