Description

Three Arbitrary Lagrangian-Eulerian codes are compared on a set of test problems. Code CHIC is based on cell-centered Lagrangian scheme while codes ALE INC and PALE are based on staggered Lagrangian scheme. Pure Lagrangian methods are first tested on Sod and Sedov problems. The full ALE methods are then compared on two more advanced problems, namely triple point and shock bubble interaction problems, which cannot be treated by pure Lagrangian method due to severe distortion of moving Lagrangian mesh.
