A parallel 3D ALE code for metal forming analyses

PDF Version Also Available for Download.

Description

A three-dimensional arbitrary Lagrange-Eulerian (ALE) code is being developed for use as a general purpose tool for metal forming analyses. The focus of the effort is on the processes of forging, extrusion, casting and rolling. The ALE approach was chosen as an efficient way to deal with the large deformations and complicated flows associated with these processes. A prototype version of the software package, ALE3D, exists and is being applied to the enumerated processes. The development of the code is being driven by the dual constraints of portability and extensibility. A general purpose simulation tool must be capable of mining ... continued below

Description

A three-dimensional arbitrary Lagrange-Eulerian (ALE) code is being developed for use as a general purpose tool for metal forming analyses. The focus of the effort is on the processes of forging, extrusion, casting and rolling. The ALE approach was chosen as an efficient way to deal with the large deformations and complicated flows associated with these processes. A prototype version of the software package, ALE3D, exists and is being applied to the enumerated processes. The development of the code is being driven by the dual constraints of portability and extensibility. A general purpose simulation tool must be capable of mining on a variety of platforms from single processor workstations to massively parallel platforms. It might also be configured to easily accommodate new physical models and parameters. The focus of this paper will be on computer science issues, with parallelization being the dominant issue. Long term goals will be described, as well as current status.
