Code

I am soon releasing an efficient and low-dependency Material Point Method code written in C++ for modeling elasto-viscoplastic materials. It is parallelized with OpenMP and easily adaptable to many problems. Many constitutive models are directly avalaible, formulated in a finite strain framework. The code is called Ma++er (pronounced Matter).
Please contact me if you are interested!
