MPoint Examples

MPoint provides continuum-based modelling based on the Material-Point Method (MPM). The method allows for large deformation without any mesh distortion.

Illustrative step-by-step tutorials, example applications and verification problems.

Tutorials

This section presents tutorials that take first-time users through basic steps of working with MPoint.

The Quick Start is a first look at model creation in MPoint that moves quickly through a series of steps to go from project creation to problem solution, and is aimed at users familiar with FLAC3D and the user interface.
