Abstract: This paper presents the theoretical basis used to develop, in AESA, a computer program to solve the direct calculation of the actuating pressure forces on a vibrating solid inside a fluid. The problem is solved both in the case of slightly compressible and incompressible fluids having reached, in the first case, a completely original solution. The above mentioned calculations are carried out using the finite element method, since it offers special advantages when carrying out, simultaneously, a study on the ship response to a determined exciting agent. As a subproduct of the said development, a computer program to obtain the potential flow developed around the hull when it moves at a determined speed, has also been elaborated.
