Users manual of programme AEW2. Southampton, UK, University of Southampton, 30pp.
(Ship Science Reports, 2).
Programme AEW2 is a digital computer programme to predict the motions and bending moments of a ship in regular and irregular waves.
The principle assumptions of the mathematical theory are that the motions can be considered as linear, and that the section shapes can be approximated by Lewis forms. These assumptions enable the strip theory to be used and as a consequence of the second assumption the two dimensional section added mass and damping coefficients can be calculated.
Section i describes the input parameters, section ii the mathematical background, section iii contains a generalized flow chart of the programme structure. In the appendices two examples are given, together with a list of diagnostic printouts that can be produced from the programme.
