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 The difference is that OSParticulas is for new features in development, for proprietary or unpublished features, and for features not yet released to the open source version.

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.
