Fluid-Structure Interaction with Splines

■概要

In order to obtain accurate and smooth shape description of moving surfaces, as well as accurate flow approximation on coarse meshes, the approach of NURBS-enhanced finite elements (NEFEM) is being applied to various aspects of moving-boundary flow computations. In NEFEM, certain parts of the boundary of the computational domain are represented using non-uniform rational B-splines (NURBS), therefore making it an effective technique to accurately treat curved boundaries, not only in terms of geometry representation, but also in terms of solution accuracy.

The use of a full NEFEM approach for the flow variables in the vicinity of the moving surface has been investigated. The applications include both production engineering, i.e., die swell in plastics processing simulation, and safety engineering, i.e., sloshing phenomena in fluid tanks subjected to external excitation. The NEFEM description couples naturally with the isogeometric analysis (IGA) approach for structures in the fluid-structure interaction context.
