Comparison of staggered and cell-centered Lagrangian and ALE hydrodynamical methods
Result 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 Sodand 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.
