Our Philosophy
Engineering Excellence
We believe in software that delivers reliable, accurate results without requiring expert tuning. SHIPFLOW is designed with sensible defaults and robust algorithms that work out of the box, allowing engineers to focus on design decisions rather than solver parameters.
Practical Solutions
Speed matters in the design process. Our multi-fidelity approach provides the right level of detail for each stage of design — from rapid optimization with BASIC to detailed RANS analysis — all within practical time frames that support iterative design workflows.
Validation & Trust
Every release of SHIPFLOW is extensively validated against experimental data from towing tanks and full-scale trials. We document our validation work in peer-reviewed publications because transparency builds trust with the engineering community.
Long-Term Support
We maintain long-term relationships with our customers. Our technical support team includes experienced naval architects and SHIPFLOW developers who understand your challenges and provide meaningful assistance, not just software troubleshooting.
Academic Excellence
Located at Chalmers University of Technology campus in Gothenburg, Sweden, we maintain close ties with the academic community. This collaboration ensures that SHIPFLOW incorporates the latest research in naval hydrodynamics while remaining practical and accessible for industrial use.
