Talk Title: Deforming Composite Grids for Fluid Structure Interactions
Abstract: For some years we have been developing an open source software framework called Overture for the solution of partial differential equations in complex moving geometry. We use overlapping grids (also know as overset or Chimera grids) to efficiently represent complex geometry with structured grids. I will begin this talk by giving a brief overview of Overture and its capabilities. The focus of the talk will be on our recent work for fluid structure interaction problems. I will describe the use of deforming composite overlapping grids for the solution of problems coupling fluid flow and deforming solids. The method is based on a mixed Eulerian Lagrangian technique. Local moving boundary-fitted grids are used near the deforming interface and these overlap non-moving grids which cover the majority of the domain. The approach is described and validated for some fluid structure problems involving high speed compressible flow and linear elastic solids.\n
