Dear RG users,
I am looking to investigate the Material Point Method in Geotechnical applications. Do you know any available software for this purpose? It can be etiher commercial or open source. Looking forward for your answers.
Best Regards
Bekir SF
There are MPM codes with different perspectives. For geotechnical analysis, in my opinion, the principal available codes are the follows:
- CB-GEO-MPM (https://github.com/cb-geo/mpm/)
- MPM3D-F90 (https://github.com/xzhang66/MPM3D-F90)
- NairnMPM (https://github.com/nairnj/nairn-mpm-fea/tree/master/NairnMPM)
- Anura 3D (http://www.mpm-dredge.eu/)
- MPM-GIMP (https://sourceforge.net/p/mpmgimp/home/Home/)
Dear Bekir,
I believe you can request a free trial of MPMsim, at http://www.mpmsim.com/
I haven't used it myself, but am curious to see how it performs.
Best wishes,
Ashley
Dear Ashley Dyson ,
I had a look on the software however it seems to be developed only for structural analysis. I am still not sure. Also, there is software called Anura3D but I think it is not publicly available.
Best Regards,
Bekir
Hi,
I recommend Uintah. It is open source and have quite lot features.
Dear Quoc-Anh Tran , thank you very much. I will definitely consider it.
It seems to me that they are still in early stage. I have seen examples in which Anura3D has already been used in the geotechnical field. My advice is to write to some components of the groups of works that collaborate in the development of these software, so you can understand the current stage of development and listen to their ratings and suggestions. Being you in the university, they could help you.
The biggest problem is that MPM currently does not have a strong theoretical underpinnings like FEM so many researchers demonstrate that sometimes MPM solutions do not converge so.
Anura3D is designed particularly for geotechnical engineering. I haven't use that and it is comercial software so I cannot look at the code to undertand it.
When I search for a software, I look at the developer team behind and see how many users use it for practical problems. And here I found Uintah as they have long-term commitment and quite decent community. Besides, it is open source so you can really look at the code to understand the algorithm and so on.
Hi Bekir,
I recomend you to use Anura 3D. Our code is not open source, but we can generate executables for you to use. If you want to manipulate the code, then you can ask any member of the Anura 3D comunity for it.
As Lei pointed out above, Anura is not a comercial software, so it is free!!
Let me know if you need more info.
Thank you very much all for your answers. Dear Luis Zambrano Can I define the material properties according to Mohr-Coulomb criterion?
Thank you.
Hi Bekir:
Could you be more specific on what issue that you would like to apply the MPM code. Some of the codes may not have the constitutive model you need. Meanwhile if you want to conduct simulation that involves high speed impact or vibration the best chose would also be different. The formula of MPM for example whether it is more suitable to use explicit or implicate method, what formula or solver you need and what is the boundary condition you want to apply. You have to narrow these things down. I do have couple of choices and codes for you but please be more specific on your needs.
Cheers

Bekir Salih Firincioglu you can use several constitutive models. We do have Morh-Coulomb.
With regards to what Yupeng Jiang said, Anura uses a explicit scheme, it can solve coupled systems (up to 3 phases), and we have different integration schemes.
Thank you for your answers Yupeng Jiang Luis Zambrano . I would like to simulate the flow like behavior of sands (soils) under certain circumstances, e.g. landslides. However, I don't have much programming skills, I may be able to do only basic interpretations.
Hi Bekir:
In that case, what you may need is explicit MPM with Drucker-prager constitutive model (instead of Morh-Coulomb). I think the codes from Luis Zambrano should be good enough for you to simulate multi-phase (unsaturated soil) media or simply add cohesive force in the D-p model. Since you do not have a strong motivation to start from a relatively bottom level of MPM, the codes I have may not be very good choice for you.
Cheers
Yupeng

Uintah software can be used to solve problems using material point method
