Abstract: A number of methods for mesh deformation in the simulation of fluid-structure interaction (FSI) are considered. The FSI problems are solved in arbitrary Lagrangian–Eulerian formulation. The capabilities of meshless interpolation algorithms for mesh node movements that provide a large deformation without degeneration of cells are analyzed.

Keywords: fluid-structure interaction; mesh deformation; Shepard method; radial basis functions; parallel computing.
