MPoint's MPM solver enables engineers to realistically model large deformation, failure progress, and post-failure movement with confidence



MINNEAPOLIS, MN, September 22, 2026 /24-7PressRelease/ -- ITASCA Software today announced the release of MPoint2D and MPoint3D, the industry's first commercially available geotechnical software products built on the Material Point Method (MPM). Designed specifically for geotechnical engineering applications, MPoint is capable of simulating large deformation, material flow, instability, and post-failure behavior that can't be captured using conventional mesh-based numerical methods.

The one-of-a-kind software provides a specialized MPM environment for evaluating how geotechnical systems behave under realistic loading conditions and through the stages of extreme deformation. By overcoming the geometric limitations associated with traditional mesh-based approaches, MPoint helps engineers move beyond simple stability assessments to understand how deformation develops, how failure progresses, and what occurs after failure initiates.

"Many of today's geotechnical problems involve significant movement, progressive failure, and material runout," said Jim Hazzard, Product Manager. "MPoint gives engineers a practical way to apply Material Point Method technology to real-world projects, helping to better understand deformation mechanisms and make more informed engineering decisions."

Advancing Geotechnical Modeling Beyond Traditional Methods

MPoint is based on a Material Point Method formulation, which tracks material points as they move through a fixed computational background grid, rather than relying on a mesh that deforms with the material and becomes distorted and needs to be rebuilt. MPM is an ideal method to analyze scenarios where the engineering question extends beyond stability to understanding how a system deforms, mobilizes, and fails.

With MPoint, engineers can simulate:

• Large deformation without mesh distortion or remeshing
• Progressive failure and localized shear band development
• Liquefaction, slumping, and material flow
• Breach initiation and post-failure runout
• Interactions between soil, rock, and water within a unified modeling framework

"Material Point Method technology has long been recognized for its ability to model large deformation and post-failure behavior, but until now, it has not been available in a commercial product designed specifically for geotechnical engineering," said Jibril B. Coulibaly, Computational Scientist. "With MPoint2D and MPoint3D, we're bringing this advanced capability into a practical engineering workflow that helps users better understand how ground systems deform, fail, and evolve over time."

Civil Engineering Applications

MPoint is particularly well suited for civil engineering projects where understanding deformation and post-instability behavior is critical.

Dam and Embankment Performance Assessment – Engineers can evaluate deformation, failure progression, breach initiation, and potential runout in earthen dams and embankments. The ability to model large movement and material flow provides valuable insight into failure mechanisms and potential consequences.

Landslide and Slope Failure Analysis – MPoint enables detailed investigation of slope instability, progressive failure development, and post-failure movement. Engineers can better understand how ground conditions, pore pressure changes, and triggering events influence landslide initiation and runout behavior.

Mining Applications

For the mining industry, MPoint provides a new tool for evaluating high-consequence geotechnical risks involving extreme ground movement.

Tailings Storage Facility Analysis – MPoint is an ideal tool to simulate tailings dam deformation, liquefaction triggering, failure progression, breach formation, and material runout to support risk assessment, design evaluation, and operational decision-making for tailings management.

Waste Rock and Mine Slope Stability Studies – Mining engineers can investigate progressive failure mechanisms in large slopes and embankments, gaining insight into deformation patterns and post-failure behavior that may not be fully represented using traditional small-strain approaches.

Built for Modern Geotechnical Engineering

MPoint was developed to address the growing need for advanced simulation tools capable of modeling extreme deformation in geotechnical systems without the complexity and computational cost of discrete element modeling. Available in both two-dimensional and three-dimensional versions, engineers can select the appropriate level of model complexity to meet their project needs.

MPoint can be used as a standalone solution for Material Point Method analysis or coupled with FLAC2D or FLAC3D, ITASCA products that have been trusted by engineers for decades. The hybrid approach combines MPM with Finite Volume methods for efficient analysis of complex geotechnical analyses of localized failure and the surrounding ground response.

"Many geotechnical problems involve understanding what happens after instability begins. MPoint was developed to provide a modeling approach that can reproduce large deformation, helping engineers evaluate post-failure ground behavior with confidence, supporting more informed design, risk assessment, and decision-making," said Tryana Garza-Cruz, General Manager, ITASCA North America.

By delivering the first commercially available MPM software specifically developed for geotechnical applications, ITASCA is providing practitioners with a practical path to more realistic simulation of complex ground behavior and the consequences of failure.
