S-ALE
The Structured ALE solver in LS-DYNA targets to solve ALE problems with structured mesh. It supports all parallel versions of LS-DYNA, i.e., SMP, MPP and MPP Hybrid. The new solver generates structured ALE mesh automatically. The elements do not have to be of equal size. Instead, a user can define element spacing according to needs of the specific engineering problems.
Adiabatic Expansion
A cylinder testd eveloped at Lawrence Livermore Laboratory (LLNL) with the aim of characterizing the adiabatic expansion of the detonation products, by measuring the motion of the cylinder wall while it is expanded by the detonation products of the explosive charge inside.
