Multi-material ALE methods in unstructured grids. (English) Zbl 0980.74068
From the summary: This paper examines algorithms required for the Multi-Material ALE (MMALE) method, and extensions to these algorithms on unstructured meshes. In addition, second-order behavior of MMALE algorithm as it exists in the high-energy-density physics code (Arbitrary Lagrangian Eulerian General Research Applications code ALEGRA) is demonstrated, along with a practical example.
