The MODEL library

Introduction

MODEL is the The Mechanics of Defects Evolution Library, a collection of free software for the study of defects in materials.

MODEL contains the following modules:

• DD_intro
• Particle Interaction Library (PIL)
• Finite Element Method (FEM)
• Simplicial Mesh module
• Numeric Quadrature module

Installation

MODEL is a header-only library, therefore you just need to have MODEL in your include path.

MODEL is written in C++ and is heavily object-oriented. In particular, some of the latest features of the C++11 standard are used. Therefore, MODEL can only be compiled by C++11-capable compilers. The following compilers should do the job:

• GNU g++ version 4.8 or above (available at http://gcc.gnu.org)
• INTEL icc version 13.0.1 or above

In order to speed up compilation time, gcc release 5 or greater is recommended.

Are you testing MODEL on Mac OsX? Then make sure you read the dedicated Mac osX page.

External libraries

The Discrete Dislocation Dynamics module of MODEL requires the following external libraries:

• the c++ standard library
• the Eigen library (header only, available at http://eigen.tuxfamily.org)
  

In order to run MODEL-DDD in parallel mode, additional libraries are needed:

• the open-MPI protocol

Other useful packages

Some bash scripts used for post-processing of pictures and videos are:

• ImageMagick
• FFmpeg

These are standard packages on most Unix/Linux distributions.

Meshes are generated using the following library:

• TetGen

See the dedicated Generating Meshes with Tetgen page for sample use.
