Learn Material Point Method (MPM): A hands-on training and coding session
October 5, 2023 | 1:00pm - 3:00pm CT
About the Webinar
This training aims to provide participants with a comprehensive introduction to the Material Point Method (MPM) and its applications in large-deformation modeling. Participants will gain hands-on experience by coding a 1D MPM using Python and utilizing the CB-Geo MPM to simulate a column collapse problem on DesignSafe. We will use ParaView to visualize the results.
Pre-requisites: Basic Python (numpy)
The Material Point Method (MPM) is a computational technique that has gained significant traction in large-deformation modeling. One of the standout features of MPM is its ability to handle the complexities of large deformations without the mesh entanglement issues commonly encountered in traditional Finite Element Methods (FEM). MPM employs a dual representation of the material: particles (Lagrangian) carry material information, while a background mesh (Eulerian) is used for computations, making it adept at handling problems with substantial deformations, such as landslides, tsunamis, and snow avalanches.
- Introduction to MPM
- Coding a 1D MPM in Python
- Running CB-Geo MPM on DesignSafe
- Visualization with ParaView
By the end of this training, participants will have a solid understanding of the Material Point Method, its advantages in large-deformation modeling, and practical experience in implementing and visualizing MPM simulations.
