Originální abstrakt

The article is devoted to the numerical modelling of the structure-fluid interaction of a solid body submerged in a fluid. It is supposed that the submerged body is absolutely rigid and that the pressure distribution in the liquid can be described by the Laplace euquation in 2D domain.The space discretization in the liquid is carried out in two ways. The first approach is based on the finite element method in the physical domain with a moving boundary (between body and liquid). The second method transforms the physical domain with moving boundary to the fixed reference domain and the transformed Laplace problem is then solved by the finite difference method. The time discretization is realized by the backward Euler method. The applicability of both approaches is verified by numerical tests.
