Wadam is a general hydrodynamic analysis program for calculating wave-structure interaction for fixed and floating structures of arbitrary shape.
A track record of success in hydrodynamics
The analysis features of Wadam represent state-of-the-art technology and the program is unsurpassed for practical applications. Airy wave theory is applied and results are presented as complex transfer functions or as deterministic results for specified phases of the wave.
Wadam is based on widely accepted linear methods for marine hydrodynamics the 3-D radiation-diffraction theory employing a panel model (created by Patran-Pre) and Morison equation in linearised form employing a beam model (created by GeniE).
The former method is appropriate for voluminous structural parts (having typical dimensions greater than 1/5 of the wavelength). The latter method will predict drag (viscous) forces more accurately and is therefore suitable for more slender structural parts.
For a structure comprised of both slender and voluminous parts the two methods may be used in combination. The user will then establish so-called composite or dual models.
By establishing a dual model in which a structure is modelled by a beam model inside a panel model the advantages of both methods may be utilised. Wadam will automatically apply the appropriate method based on the ratio of the structural dimension (diameter) to wavelength.
The radiation-diffraction part of Wadam is based on software developed by Massachusetts Institute of Technology.
Wadam is often executed from HydroD where graphic modelling of the environment is done.
