Marine Engineering Meets CFD

with Simuneer and Cadence Fidelity® Marine Solver

Fluent by design: CFD software for shipbuilding and offshore

Fidelity CFD is specially designed for hydrodynamics in shipbuilding and offers numerous smart features: integrated hydrostatics, kinematic couplings between bodies (e.g. hull, propeller, rudder, etc.) or the C-Wizard as an extra tool for automated setups. This allows you to create typical use cases in just a few minutes - for fast, reliable results.

Stable workflow — from concept to validation

Resistance, propeller-hull interactions, swell, maneuvering, cavitation: our marine workflows cover all tasks - without tool hopping or trial-and-error. This allows you to compare designs faster and make informed decisions. Do you need help getting started? No problem, we can advise you and develop individual workflows and standards for your use cases.

Adaptive Grid Refinement for even more precision

The integrated Adaptive Grid Refinement (AGR) automatically refines your computational grid during the runtime of the CFD solver. In combination with stable-performing RANS solutions, you achieve fast convergence and reliable results with efficient computing time.

The integrated Adaptive Grid Refinement (AGR) automatically refines (or coarsens!) your computational grid during the runtime of the CFD solver. Triggered by physics, the finest flow details can be resolved without prior knowledge of the exact position. A real game changer in terms of computational efficiency.

Fidelity CFD Platform

Specialized modules for marine simulation

Fidelity Fine Marine — Solver (Marine)

A tool for all waters: Fine Marine is the tool for all shipbuilding and offshore applications (and sometimes beyond).

  • Numerical towing tests or propulsion calculations with propellers and pod drives, maneuvers in rough seas, interactions between attachments and ESDs or cavitation investigations: Fine Marine always delivers reliable results
  • Extremely precise thanks to AGR (Adaptive Grid Refinement)
  • Set up quickly with the CWizard

Hexpress — Meshing (unstructured)

Hexpress is the unstructured mesher in Fidelity®: It generates hexahedron-dominant or purely hexahedral meshes for complex geometries.

  • Unclean CAD can be meshed directly without time-consuming preparation
  • Thanks to efficient parallelization, solver-friendly, high-quality networks are created in a short time, even with high cell counts
  • Ideal for fast Pre-Processing workflows

Autoseal — Pre-Processing (CAD)

Autoseal automatically closes any complex holes in the geometry, preserves geometry details and immediately delivers meshable, closed volumes.

  • Closes holes due to missing components and unclean CAD
  • 1-Click Solution — without tedious manual work
  • Shortens (the) preparation time of complex models from days to hours

More reasons to choose Fidelity CFD:

  • Modern, intuitive user interface
  • Combine structured and unstructured networks
  • Automatic switching between structured and unstructured algorithms per domain
  • Faster convergence for low velocity flows thanks to pressure-based solver
  • In-situ co-processing and local post-processing
  • Complete automation via the Python API

Highlights

With the extended multi-domain functions in Fidelity Marine, fluid properties and free surfaces for LNG tankers can be defined individually for each domain – for maximum flexibility and realistic simulation of complex tank systems.

Link to the life hack

Damen Shipyards (www.damen.com) is an international shipbuilding group with more than 50 shipyards in over 120 countries. While CFD simulations for the resistance of bare hulls have long been their daily business, they are now dealing with more complex simulations such as propulsion and maneuvering. With the help of Cadence’s CFD and cloud solutions, they now perform CFD simulations at all stages of construction.
