Original Abstract
The paper concerns problems, in which both the structural and fluid responses of a complex construction to mechanical actions are strongly coupled. Particularly, there are treated problems, in which the structural dynamic response to actions is significantly affected by the presence of the fluid in the structure. The work presents the evolution of the way of solving that problem of the complex solution of the generalized problem of the structure using multiphysical ANSYS program package. The formulation of fluid finite elements is discussed, considering both pressure (Euler) and displacement (Lagrange) approaches. The solution is demonstrated on water tower structure.
Keywords
Fluid structure interaction, eigenmode, Euler fluid, Lagrange fluid.
