An algorithm for permanent fluid-structure interaction in explicit transient dynamics
The paper presents the strategies and models adopted in the PLEXIS-3C computer code for the description of interactions of the permanent type between fluids and structures in fast transient dynamic problems. The method is implemented via an algorithm able to deal automatically with situations of large geometrical complexity, such as those encountered with box-like structures (multiple interactions, structural bifurcations or even arbitrary structural intersections and submerged structural edges) in the presence of large structural displacements, rotations and deformations. The algorithm dramatically reduces the amount of information that has to be supplied to describe a given interaction. As a consequence, the time and effort needed for input preparation in large and complex, realistic simulations, is substantially reduced and the possibility for human error is almost eliminated. Several examples show the application of the method to problems of practical interest.
