To request new material, or changes to any of the existing material, please send us an email here. We are happy to generate new materials and give assistance where possible. If you are requesting help for NDDEM, you can also post your question as an Issue on github here. You can do the same for the mapping toolbox here.
The examples on this page have been put together by Dr François Guillard and Dr Benjy Marks at The University of Sydney. We are part of the Sydney Centre in Geomechanics and Mining Materials, and are passionate about the education of engineers, physicists and mathematicians in the field of granular mechanics.
