Flexible CFD solution for maritime applications.
HELYX-Marine is an extension module for HELYX developed by ENGYS in conjunction with Prof. Kevin Maki of the Department of Naval Architecture and Marine Engineering of the University of Michigan, USA.
The module incorporates a comprehensive set of CFD solvers and simulation tools to cover the main aspects ship hydrodynamics and design optimization of naval and many maritime applications.
EXCEPTIONAL VALUE
Designed for non-CFD experts. Automated templates to enhance productivity.
Automated templates
HELYX-Marine offers automated templates for calm-water resistance and seakeeping simulations, built on validated data and best practices by ENGYS. Extensive validation across multiple marine projects ensures accurate results for ship design applications.
Accurate results, streamlined workflow.
Easy-to-use GUI
The HELYX-Marine GUI offers a streamlined workflow for ship design, featuring tools for calm-water resistance, seakeeping, and self-propulsion analysis. Its user-friendly interface, supported by ENGYS' expert technical assistance, ensures a smooth experience for naval engineers, allowing non-CFD experts to achieve accurate results efficiently.
No CFD-expertise needed.
No more waiting in line
Traditional CFD software limits you to one simulation at a time unless you pay for expensive HPC licenses. With HELYX and HELYX-Marine, there are no such limits. You can run multiple ship design variations simultaneously and manage pre- and post-processing tasks seamlessly, thanks to our unlimited scalable licenses.
No more bottlenecks, just pure efficiency.
Calm-water resistance
HELYX-Marine for calm-water resistance simulations.
Accurate VOF solver.
HELYX-Marine offers an accurate non-linear RANS Volume-Of-Fluid (VOF) solver for predicting calm water behavior in both model and full-scale resistance tests. It uses Adaptive Mesh Refinement (AMR) coupled with a 6 Degrees of Freedom (DoF) motion library to predict forces, hull motion, wave patterns, and free surface elevation.
Linearized free-surface solver.
Additionally, a linearized free-surface solver is available for calm water resistance, combining RANS viscous flow near the hull with a boundary condition for free-surface elevation. This solver is suitable for low Froude numbers and slender hulls, offering fast turnaround times, ideal for automated hull form optimization.
Seakeeping
HELYX-Marine for seakeeping analysis.
HELYX-Marine features an advanced seakeeping designed for simulating the motion of a body on or near the air-water interface. It solves the six-degree-of-freedom equations of motion and is suitable for a wide range of problems, including the free-fall of a body that impacts the air-water interface, for the seakeeping response of a surface vessel or submarine, or for the manoeuvring response of a ship. A set of regular and irregular wave generation libraries is provided and an efficient implicit relaxation zone implementation to tackle the most difficult problems such as water impact, breaking waves and waves reflection. The solver is coupled with an AMR library to ensure accurate resolution of dynamically changing free-surface patterns.
Self-propulsion
HELYX-Marine for self-propulsion analysis.
To address the hull-propeller interaction, HELYX-Marine provides an advanced solver for self-propulsion modelling. Users can choose to model the actual discretised propeller using a precise sliding mesh approach or opt for an efficient body-force actuator disk model to replicate conditions resembling propulsion test models or full-scale scenarios as an alternative to sea trials. To achieve realistic test conditions, the software includes an efficient PID controller. This controller allows users to adjust the propeller revolution speed to match either a target cruising speed or a skin friction correction force.
