John A. Nairn Research Software

This project contains the computation mechanics software originating from John A. Nairn's research group at Oregon State University.

Computational Mechanics Code Engines

The code engines NairnFEA and NairnMPM do finite element analysis (FEA) and material point method (MPM) calculations. They are platform-independent C++ code projects. The FEA engine is static, linear elastic, and 2D. The MPM engine is 2D or 3D, is dynamic, and can handle any defined material types.

Java Application for Pre- and Post-Processing

Another component of this project is the Java application called NairnFEAMPMViz. This application can edit XML files for input to the code engines, submit jobs, and once done, visualize and display the results.

MacOS X Complete Package - NairnFEAMPM

If you are working on a MacOS X computer, you can download the entire computational mechanics package as binaries self contained within an application for setting up, running, and visualizing calculations. The MacOS X application is called NairnFEAMPM. It is now available as a free download from the Mac App store, or you can download by visiting the NairnFEAMPM web site.

When working with source code on a Mac, you should still download the NairnFEAMPM application and use it in place of the NairnFEAMPMViz application. The NairnFEAMPM software has more robust features than NairnFEAMPMViz, including options for 3D graphics. To work with source code when using NairnFEAMPM, see its help information on "Code Engine Development."

Documentation Files

All features of the software are documented in the project.
