OSParticulas

OSParticulas and NairnMPM are both MPM code engines. The difference is that OSParticulas is for new features in development, for proprietary or unpublished features, and for features not yet released to the open source version.

New OSParticulas Features

Some of the features in development and/or only available in OSParticulas are:

• A new neo-Hookean, hyperelastic material model.
• MPM modeling with membranes in both 2D and 3D simulations.
• Ability to set position-dependent initial velocities on particles.
• Ability to set time- and position-dependent body forces on the grid.
• A new way to create boundary conditions when using rigid material particles for moving boundary conditions.

Using OSParticulas

OSParticulas is available to members of the OSU MPM Consortium and selected collaborators with the the research group of John A. Nairn ar Oregonstate University. For details, you can contact us with an email.

OSParticulas Documentation

This wiki site documents both OSParticulas and NairnMPM; features that are only available in OSParticiulas will be noted. Those enabled to use OSParticulas can check the documentation notes in their download for any additional setup steps and for instructions on using any extra features available in OSParticulas that are not yet written up in these wiki pages.
