A simple and robust C++ code for the material point method (MPM) called Karamelo is presented here. It was designed to provide an open source, fast, light and easy-to-modify framework for both conducting research on the MPM and research using the MPM, instead of a finite element package. This paper presents the overall philosophy, the main design choices and some of the original algorithms implemented in Karamelo. Simulations of solids and fluids involving extreme deformation are provided to illustrate the capabilities of the code.

Karamelo：用于材料点方法的开源并行C ++程序包

这里介绍了一个简单而健壮的用于材料点方法（MPM）的C ++代码，称为Karamelo。它旨在为进行MPM的研究和使用MPM的研究（而不是有限元程序包）提供一个开源，快速，轻便且易于修改的框架。本文介绍了总体思想，主要设计选择以及在Karamelo中实现的一些原始算法。提供了涉及极端变形的固体和流体模拟，以说明代码的功能。
