NairnMPM

NairnMPM is the open-source code engine in this package for doing material point method (MPM) simulations. It is object-oriented C++ code that can run on many platforms. The main calculations are parallel code. You run calculations by creating Input Files for MPM Calculations. Once the calculations are done, you have a variety of options for visualizing and analyzing the output.

NairnMPM does 2D, axisymmetric, and 3D simulations with a wide range of material types. Some of its features are (click each link for details):

• Many material models including elastic, plastic, isotropic, anisotropic, viscoelastic, small strain, and large strain.
• Explicit Cracks, Fracture Mechanics, and Cohesive Zones
• Multimaterial Mode
• Models from Images
• Coupled Diffusion and Conductivity
