Updates to Oakley Application Software - September 2015

OSC is refreshing the software stack on Oakley on September 15, 2015 (during the scheduled downtime); something we have not done since Oakley entered service in 2012. During the software refresh, some default versions are updated to be more up-to-date and some older versions are removed. Information about the old and new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage. See



LS-PrePost is an advanced pre and post-processor that is delivered free with LS-DYNA. The user interface is designed to be both efficient and intuitive. LS-PrePost runs on Windows, Linux, and Unix utilizing OpenGL graphics to achieve fast rendering and XY plotting. The latest builds can be downloaded from LSTC's FTP Site.


User-Defined Material for LS-DYNA

This page describes how to specify user defined material to use within LS-DYNA.  The user-defined subroutines in LS-DYNA allow the program to be customized for particular applications.  In order to define user material, LS-DYNA must be recompiled.


LS-DYNA with user defined material models are only available on the Glenn Cluster.


The following versions on Glenn are available for use with user defined material models:


CFX is a computational fluid dynamics (CFD) program for modeling fluid flow and heat transfer in a variety of applications.

Availability and Restrictions

CFX is available on Oakley and Glenn Clusters. The versions currently available at OSC are:


STAR-CCM+ provides the world’s most comprehensive engineering physics simulation inside a single integrated package. Much more than a CFD code, STAR‑CCM+ provides an engineering process for solving problems involving flow (of fluids and solids), heat transfer and stress. STAR‑CCM+ is unrivalled in its ability to tackle problems involving multi‑physics and complex geometries.  Support is provided by CD-adapco. CD-adapco usually releases new version of STAR-CCM+ every four months.


LS-DYNA is a general purpose finite element code for simulating complex structural problems, specializing in nonlinear, transient dynamic problems using explicit integration. LS-DYNA is one of the codes developed at Livermore Software Technology Corporation (LSTC).


COMSOL Multiphysics (formerly FEMLAB) is a finite element analysis and solver software package for various physics and engineering applications, especially coupled phenomena, or multiphysics. owned and supported by COMSOL, Inc.
