Calculate fluid potential fields associated with the theory of added mass [R4.07.03],

The fields are induced by a perfect, incompressible fluid, at rest or in potential flow, on a 3D structure.

The terms in these fields are calculated based on the modal basis of the structure in the void.

The calculation of the terms of the matrices is carried out by solving the equations of LAPLACE in the context of a thermal analogy. The calculated temperature plays the role of pressure in the fluid domain. It is therefore necessary to take care to define the fluid material by thermal characteristics, and assign a thermal model to the part of the mesh that represents the fluid.

Thanks to this operator, it is possible to determine, for example, the pressure created by the fluid on the vibrating structure according to one of its specific modes.

Test FDLV114b offers an example of implementation on a cylindrical tank case.

Produces an evol_ther-like data structure.
