Abstract
This paper describes the coupling of FEFLO, a general purpose compressible and
incompressible flow solver based on adaptive unstructured grids, with SIMPACT, a
general purpose, large deformation, explicit structural dynamics code developed at
the Center for Numerical Methods in Engineering (CIMNE). Details on the codes
as well as the coupling strategy employed are given. An example illustrates the
possibilities the coupled codes offer.
1 Introduction
The ability to predict accurately fluid-structure interaction problems is of fundamental
importance for design, analysis and reconstruction inmany areas of mechanical
and civil engineering. In order to characterize the effects of an accidental
or intentional explosion close to a building, a coupled fluid-structure interaction
calculation has to be carried out. The present effort presents the coupling of FEFLO,
a general purpose CFD solver with SIMPACT, a general purpose explicit CSD
code.
2 FEFLO
FEFLO was conceived as a general-purpose CFD code based on the following
general principles:
- Use of unstructured grids (automatic grid generation and mesh refinement).
- Finite element discretization of space.
- Separate flow modules for compressible and incompressible flows.
