Throughout the marine industry, there are many design and optimization challenges. Many of which can be further understood and solved by leveraging CFD simulation effectively. In a webinar, Paolo Geremia discussed ENGYS’ efforts towards enabling the marine industry to perform complex simulation and analysis tasks with HELYX and HELYX Marine Add-On to:
- Quickly Evaluate Designs via Calm-Water Resistance (CWR) Analysis: Using a Linearized Free-Surface (LFS) solver, HELYX Marine is able to quickly and accurately measure calm-water resistance at low Froude numbers. The benefit of the LFS solver is that can be as much as two orders of magnitude faster than a volume of fluid (VOF) solver with the same accuracy.
- Optimize Hull-Form Shape: The LFS solver requires much less computational resources and simulation time compared to a standard volume of fluid (VOF) free-surface solver. As a result, the LFS solver can be combined with optimization to determine the best shape to minimize drag on a hull at desired speeds.
- Analyze Design Behavior During Dynamic Wave Conditions: Perform seakeeping analysis by leveraging the advanced mesher in HELYX; volume of fluid (VOF) solver; dynamic 6 degrees of freedom (6DoF) capability; and wave generation tools.
Beyond calm-water analysis, seakeeping analysis, and optimization, there are tools for modelling cavitation, propulsion, and hydroacoustic phenomena. If you’re interested in any of the topics mentioned here or in the webinar, reach out to ENGYS for a live demonstration. We are happy to discuss proof-of-concept projects to show how HELYX and HELYX Marine can replace other commercial tools.
