Arbitrary Lagrangian-Eulerian 3D and 2D Multi-Physics Code

ALE3D is a 2D and 3D multi-physics numerical simulation software tool using arbitrary Lagrangian-Eulerian (ALE) techniques. The code is written to address both two-dimensional (2D) and three-dimensional (3D) problems using a hybrid finite element and finite volume formulation to model fluid and elastic-plastic response on an unstructured grid.

The ALE and mesh relaxation capability broadens the scope of applications in comparison to tools restricted to Lagrangian or

Eulerian (advection) only approaches, while maintaining accuracy and efficiency for large, multi-physics and complex geometry simulations. Beyond its foundation as a hydrodynamics and structures code, ALE3D has multi-physics capabilities that integrate various packages through an operator-splitting approach.

Additional ALE3D features include heat conduction, chemical kinetics and species diffusion, incompressible flow, wide range of material models, chemistry models, multi-phase flow, and magneto-hydrodynamics for long (implicit) to short (explicit) time-scale applications.

Lawrence Livermore National Laboratory is offering two ALE3D classes this fall.

ALE3D INTRODUCTORY CLASS – Aug. 27-30, 2019 – $1,800
This introductory class will cover the basics of running the code and describe some of the theory behind its various physics modules. There will be a mix of lecture and hands-on training during the three days. The target audience is those who have performed some computational modeling. Some experience running ALE3D is helpful, but not required.

ALE3D ADVANCED CLASS – Sept. 23-27, 2019 – $2,200
This will be a five-day advanced class in the use of ALE3D. While many of the topics presented here are presented in the introductory course, this class will cover these topics in much greater detail. There will be a mix of lecture and hands-on training during the five days. The target audience is those who are users of ALE3D, and previous attendance of the introductory ALE3D course is highly encouraged.

ALE3D is a limited access code. No foreign nationals please.
