This starts with a reminder of the October 22 North Shore Technology Council Sustainable Energy Business Breakfast, then reviews the Gmsh FEM pre/post-processing program, revisits the libMesh and deal.II finite element libraries, and describes recent additions to

Opennovation News August, 2008 August 29, 2008

This issue describes the Debian 5.0 "Lenny" freeze, the North Shore Tehcnology Council Fall 2008 breakfast forum schedule, the deal.II finite element analysis library, and a number of recent releases of open source engineering software.

Opennovation News July, 2008 July 30, 2008

This issue discussed the Bentham Open Acces Journals; reminded readers of the Call for Papers for an Open Source materials symposium; reviewed Code_Aster, and introduced the Opennovation Ubuntu repository.

Opennovation News May, 2008 May 30, 2008

This issue started with two TMS articles: a JOM paper, and the Call for Papers for an Open Source materials symposium; also an “under the hood” review of libMesh, an update to, and a correction to the April issue.

Call for Papers: Open Source Tools for Materials Research and Engineering May 9, 2008

The 2009 TMS Annual Meeting will include the symposium "Open Source Tools for Materials Research and Engineering" organized by Adam Powell and Kim Ferris. Abstracts are due on July 15 and must be submitted via CMS-Plus.

ATAT is not free software May 2, 2008

Francesco Poli has pointed out that the ATAT code mentioned in the April Opennovation News and the JOM article is not GPL as I (Adam Powell) had thought. Its license is given in the manual as "The files in this distribution cannot be further distributed either in their original or in a modified form without the consent of the author, Axel van de Walle (" I have removed it from the list and will include a correction in the May Opennovation News.

New Article: Open Source Software for Materials and Process Modeling May 1, 2008

An article with the above title by Adam Powell and Raymundo Arroyave appears in the May issue of JOM, the monthly journal of the Minerals, Metals and Materials Society (TMS). This article focuses on the use of open source tools for modeling of materials and materials processes in particular. The editors selected it to be this month's open access article, making it freely available to the world.

Opennovation News April, 2008 April 29, 2008

The National Academies ICME report led off this issue, followed by OpenCASCADE, the restoration of Babel to Debian, updates to, Ubuntu Hardy Heron, and the Walk for Hunger.

Integrated Computational Materials Engineering April 24, 2008

The U.S. National Academies Committee on Integrated Computational Materials Engineering (ICME) released its final report yesterday.  ICME is a new paradigm for combining computational materials science at different lengthscales to solve industrial problems.  For example, Ford's Virtual Aluminum Casting effort combines quantum mechanics, dislocation mechanics, structure formation, and macroscopic metal flow and heat transfer to predict the presence of defects and probability of fatigue failure in large castings such as engine blocks.

In addition to the value of this paradigm to industry, ICME is particularly interesting to Opennovation because although proprietary codes dominate industrial simulations of macroscopic processes, several open source codes are best-in-class for quantum mechanics, molecular dynamics, and statistical mechanics calculations, and will likely remain that way due to their copyleft licensing.

Opennovation Principal Adam Powell is a co-author of the National Academies report, and also wrote the Wikipedia article on ICME.

CAELinux includes new Salomé version 3.2.9 April 10, 2008

Though the Salomé binary version 3.2.9 is available from CAELinux, the Salomé website still only has the source code for 3.2.6. This page will be updated when the 3.2.9 source is posted.
