The rvesimulator aims to provide a user-friendly, automated Python-based framework conducting Representative Volume Element (RVE) simulation via powerful Finite Element Method (FEM) software Abaqus. By utilizing this repository, large amount of reliable FEM data-set generation is possible with RVEs encompassing materials from elastic to plastic composites .

rvesimulator provides:

1. A cross-platform function to run arbitrary Python-Abaqus script without graphical user interface (GUI), it offers users a convenience way to run their unique scripts
2. Python-Abaqus scripts to simulate RVE with different design of experiments including various micro-structures, material laws, and loading;
3. Benchmarks of running prevalent RVEs covering elastic, hyper-elastic, plastic materials are provided, which illustrates the general pipeline (preprocess, execution, and postprocess) of the developed framework

This idea of the repo is shown by the following figures:

rvesimulator is an open-source Python-based framework for RVE simulation via ABAQUS secondary development. It is noted that ABAQUS 2021 is used in the development. In order to conduct RVE simulation via rvesimulator , basic knowledge of ABAQUS usage, especially Python scripting, is required. Meanwhile, basic understanding of RVE simulation is also required. Several examples are provided in the Tutorials where users can learn the basic usage of rvesimulator. If the user wants to develop their own RVE simulation, the Documentation provides a detailed description on how to adapt the framework to their own needs.
