The Free-Lagrange Method
Abstract
Various papers on the Free-Lagrange method are presented. Individual topics addressed include: Free-Lagrange methods for compressible hydrodynamics in two space dimensions; finite difference operators on unstructured triangular meshes; a Lagrangian method for the incompressible Navier-Stokes equations on a periodic domain; Free-Lagrangian methods, independent time steps, and parallel processing; three-dimensional algorithms for grid restructuring in Free-Lagrangian calculations; and three-dimensional Free-Lagrangian hydrodynamics. Also discussed are: a vectorized 'near neighbors' algorithm of order N using a monotonic logical grid; data structures and vectorization in a two-dimensional Free-Lagrangian code; solution adaptivity using a triangular mesh; recent developments in FEM-CFD; a conservative Free Lagrange code; and compressible Lagrangian hydrodynamics without Lagrangian cells.
