CFD in Naval Hydrodynamics, Off-Shore and Wave Modelling with OpenFOAM

hjasak · April 26, 2016, 05:17

Wikki Ltd. is pleased to announce an industry focused User Day dedicated to

The User day will be held on 23 May 2015 in London.

The objective of the User Day is to present the capabilities of the Naval Hydro Pack produced by Wikki. The Naval Hydro Pack extends the capabilities of foam-extend, a community driven fork of OpenFOAM® in naval hydrodynamics CFD applications such as wave and current loading on fixed and floating ship hulls and off-shore structures, coastal wave dynamics and wave scour simulations.

Focus will be given to the presentation of validation and verification results, user testimonials and mesh generation issues for a range of naval hydrodynamics problems. The event includes the reports from

Offshore Technology Conference (OTC), 2-5 May 2016
SHOPERA: 3rd Public Workshop 13-15th April 2016
Tokyo 2015: A Workshop on CFD in Ship Hydrodynamics, 2-4 December 2015
TULCS EU FP 7 Project: Tools for Ultra Large Container Ships
In-house validation and verification

and examples of the use of FOAM naval hydrodynamics tools over a range of validation and design studies:

1) Naval hydrodynamics with FOAM: overview of physical modelling

2) Naval hydrodynamics simulations
Sloshing, slamming and water wave impact on structures
Green water simulations
Steady resistance simulations of ship hulls
Sinkage and trim simulations
Drift angle simulations
Forced oscillation simulations and constrained motion cases (heave and roll damping)

3) Meshing with Pointwise

4) Wave modelling in free surface flows
Incoming wave conditions: regular and irregular waves
Coupling of incoming waves with CFD flow simulations: relaxation zone approach
Implementation and validation of the SWENSE solver for seakeeping simulations
Sea-keeping simulations for ship hulls

5) Irregular sea states and freak wave modelling
Wave packet focusing techniques and irregular and 2-D sea state spectra
Higher Order Spectrum solver in FOAM
Generation of freak waves
Freak wave impact on fixed and floating objects

6) Constrained objects and maneuvering simulations:
Interface to external wave modelling and mooring system solvers
Global performance simulations for spar and semi-sub platforms
Modelling of ship propulsors
Simulation of free sailing and prescribed trajectory

7) Compressibility effects in free surface flows

The Workshop shall be followed by an open floor discussion of results and further physical modelling in free surface flows for off-shore and naval hydrodynamics. Hands-on trial of the Naval Hydro Pack will be available during the User Day

During the User Day, hands-on session with the Naval Hydro pack shall be available.

Invited speakers

Prof. Hrvoje Jasak, Wikki Ltd: presenting the Naval Hydro pack produced by Wikki
Dr. Steven Downie, Arup: presenting experiences of the use of OpenFOAM® in off-shore simulations
Mr. Vuko Vukcevic, Uni Zagreb: presenting seakeeping and added wave resistance results and implementation of the SWENSE solver

Good day

Could someone please provide details on how to access/obtain Naval Hydro Pack? I have installed foam-extend 4.0 (ubuntu 16.04) and OpenFOAM 4.1.

Regards
JFM
