I want to make further study about the material point method in Geotechnical Engineering (such as earthquake), but I don't know which software to choose. I contacted anura3d first, but I still need secondary development to realize the loaded seismic wave boundary conditions(versus time). I just knew the CB-Geo MPM and found that this software seems to meet the requirements. This is my first time learning FORTRAN and C + + , so I want to ask which one is a better choice.
Hi Zhao, as you mention in Anura, you will need to develop subroutines to impose a seismic load and absorbing boundary conditions and the like. However, Anura3D uses GID to define model geometry, materials, and BCs, making it user-friendly. Besides, the community behind Anura is very responsive and helpful, and you could find collaborators to tackle your needs.
I'm not so familiar with CBGeo in terms of seismic BCs, but my understanding is that you may also need to code at some level. I also know that CBGeo is better for parallel computing than Anura.
Anura3D is easier to use due to the use of the GID interface and its documentation with some examples. On the other hand, CB-GEO is a command line program designed to perform high performance calculations. If you want to run large scale simulations (large number of material points), the answer is CB-GEO. I'm not totally sure the status of these implementations, but I think CB-GEO has seismic and also absorbent boundary conditions working on.
