Anura3D MPM Research Community

Numerical modelling and simulation of large deformations and soil–water–structure interaction using the material point method (MPM)

Welcome to the Anura3D Community Portal. On this portal you can find all relevant information about the Anura3D MPM Research Community and Anura3D MPM Software. But more than only being a means of communication among developers, clients, consultants and project leaders, it is also a way to connect with users around the world, discuss new (innovative) applications and be a source of inspiration.

ASCE Engineering Mechanics Institute International Conference - 5-8 April 2020 - mini-sympossium on MPM

There is increasing interest in the MPM (and its variants, such as GIMP, CPDI1, CPDI2, etc.) as a means of modelling problems in which very large deformations occur, e.g. in the study of landslides. The purpose of this mini-symposium is to provide a forum for presenting advances in the method, e.g. improving the accuracy (including convergence and benchmark problems), dealing with numerical issues, modelling of coupled problems, computational efficiency and applications to real world problems. Abstracts will be accepted until at least the end of November (https://sites.durham.ac.uk/emi2020-ic/abstracts-submission/).

2nd International Conference on the Material Point Method (MPM2019)

08-10 January 2019
Churchill College, Cambridge, United Kingdom

We are delighted to invite you to join us at the Second International Conference on the Material Point Method for “Modelling Large Deformation and Soil–Water–Structure Interaction” organised by the Anura3D MPM Research Community in January 2019 in Cambridge. This is the second conference following the successfull first event in Delft (2017).

The aim is to provide an international forum for presenting and discussing the latest developments in both the fundamental basis and the applicability of state-of-the-art computational methods that can be effectively used for solving a variety of large deformation problems in geotechnical and hydraulic engineering. Special focus is on the numerical modelling of interaction between soils, water and structures where the interface and transition between solid and fluid behaviour plays an essential role.

For more information and the latest news regarding the conference programme and registration, please visit our website at mpm2019.eu.

We are looking forward to welcoming you in Cambridge in January 2019!

Training Course 2018 - Barcelona

Modelling large deformation and soil–water–structure interaction using the material point method

Friday, 8 June 2018
Universitat Politècnica de Catalunya (UPC), Barcelona, Spain

Large deformation and soil–water–structure interaction problems exist in many environmental and civil engineering problems, such as landslides and slope instabilities, installation of piles in saturated soils, settlement due to consolidation processes, fluidisation and sedimentation processes in submerged slopes, internal erosion in dykes, and scouring around offshore structures.

The material point method (MPM) is a numerical approach capable of modelling large deformations and, within the framework of the Anura3D MPM Research Community, it has been further developed to cope with soil–water–structure interaction.

The Anura3D v2017.2 MPM software uses a dynamic explicit MPM formulation. It is capable of simulating 1- and 2-phase materials and free surface water. A fully coupled hydro-mechanical approach is implemented to model the interaction between soil and water phases in saturated porous media. Contact problems can be solved using a contact algorithm. A library of constitutive laws is included as well as an interface for external user defined soil models.

Course participants will gain experience as users of the Anura3D v2017.2 MPM software. During training lectures, the attendees will learn first-hand capabilities of MPM by means of a set of practical exercises that will be undertaken following a tutorial specially designed for the course. The tutorial will include the following exercises:
