Abstract

An Eulerian-Lagrangian approach for large deformation fluid structure interaction problems, Part 2: multi-physics simulations within a modern computational framework T.Harmanl, J. E. Guilkeyl, B. Kashiwa2, J. Schmidt1 & P. McMurtryl I Dept. of Mechanical Engineering, University of Utah, Salt Lake City, USA "heoretical Division, Los Alamos Natl. Laboratory, Los Alamos, USA Abstract A tightly coupled fluid-structure interaction (FSI) solution technique incorporating fluid and solid mechanics, phase change and chemical reactions is presented. The continuum equations are solved with a cell-centered, multi-material ICE solution method. This formulation is integrated with a Lagrangian, particle based, solid mechanics technique, known as the Material Point Method, as described by Kashiwa et al. [I] and Guilkey et al. [2]. The combined method can handle large deformations and phase change within a single grid, without the need of separate domains for fluids and solids, or the passing of boundary cond
