摘要：
A discontinuous-Galerkin method for large deformation fluid-structure interaction problems is developed. The fluid-structure interface can be arbitrarily aligned relative to the fluid grid. An Eulerian description is used for the fluid with a Lagrangian description of the solid. Results are presented for several examples that show excellent agreement with immersed/fictitious element methods. Copyright (C) 2008 John Wiley & Sons, Ltd.
