Simulation for Wave Tank
Wave Tanks of hydro-dynamic laboratories are mainly used to test (on scale) ships in waves that should be as realistic as possible. Computer simulations can increase the operationability: simulate desired waves a priori to the experiment, or derive statistical properties from long simulations.
LabMath-Indonesia develops a software for simulating water wave very efficiently and accurately, the so-called HAWASSI-AB (Hamiltonian Wave -Ship &-Structure Interactions – Analitical Boussinesq).
HAWASSI-AB is perfectly suited for such simulations
- Exact dispersion for all wave lengths
- Nonlinear effects 2nd, 3th and 4th order
- Breaking waves
- Varying bathymetry
- Inclusion of (partially reflecting) wall
- Run-up
- Post-processing for force calculations
Examples of simulation vs experiment in hydrodynamic wave tank:
The video shows an experiment of focusing wave group (breaking) that is performed in TU Delft, the Netherlands, wave tank. The HAWASSI-AB is used for designing the signal. Plots in the right part show the measurement and simulation matched very well.

The video shows a simulation of splling wave breaking above a sloping bottom by using HAWASSI-AB software. The simulation results are compared with experimental data of Ting & Kirby 1994.

The animation shows the simulations of irregular wind waves that propagate above an uneven bottom (a slope with steepness 1:20) performed using HAWASSI software. The simulation results are compared with experimental data from MARIN (Maritime Research Institute Netherlands). After 2 hours of simulation, the simulation results still match the experimental data.
