First Paragraph of Introduction
This paper presents a procedure for computing fluid-structure interaction
problems when the boundaries of the domain undergo large displacements. The algorithm
is based on both mesh motion and mesh adaptation techniques. More specifically,
we use a node repositioning algorithm based on an elastic analogy together with a mesh
adaptation procedure based on local mesh modifications. This paper also includes a
new technique for eliminating sliver tetrahedra. Some computational results are finally
presented that include statistics on mesh quality measures.
