Abstract

While computational homogenization via FE² is a useful multiscale modelling tool for many fields, conventional implementations often require an expert level of user involvement. To address this, this work presents a Python script repository to easily set up Direct FE² input files for multiscale modelling in Abaqus. The scripts take in user inputs defining the macroscale problem along with its microscale RVE and returns an Abaqus input file that can be readily submitted for analysis. As Direct FE² uses only functions which are readily available in Abaqus to perform computational homogenization, no user-defined subroutines are required. This repository seeks to provide researchers in various fields ease of access to multiscale modelling as a tool to enhance their work. Furthermore, it aims to foster collaboration between researchers working on the Direct FE² method and further promote its development.

一个Python脚本库，用于在Abaqus中使用Direct FE2进行多尺度建模

虽然通过FE2进行计算均匀化在许多领域是一种有用的多尺度建模工具，但传统的实现通常需要专家级的用户参与。为了解决这个问题，这项工作提出了一个Python脚本库，可以轻松地在Abaqus中设置多尺度建模的直接FE2输入文件。这些脚本接受定义宏观问题及其微观RVE的用户输入，并返回一个Abaqus输入文件，该文件可以随时提交以供分析。由于Direct FE2只使用Abaqus中现成的函数来执行计算均质化，因此不需要用户定义的子例程。该存储库旨在为各个领域的研究人员提供方便的多尺度建模工具，以增强他们的工作。此外，它旨在促进研究直接FE2方法的研究人员之间的合作，并进一步促进其发展。

期刊介绍： SoftwareX aims to acknowledge the impact of software on today''s research practice, and on new scientific discoveries in almost all research domains. SoftwareX also aims to stress the importance of the software developers who are, in part, responsible for this impact. To this end, SoftwareX aims to support publication of research software in such a way that: The software is given a stamp of scientific relevance, and provided with a peer-reviewed recognition of scientific impact; The software developers are given the credits they deserve; The software is citable, allowing traditional metrics of scientific excellence to apply; The academic career paths of software developers are supported rather than hindered; The software is publicly available for inspection, validation, and re-use. Above all, SoftwareX aims to inform researchers about software applications, tools and libraries with a (proven) potential to impact the process of scientific discovery in various domains. The journal is multidisciplinary and accepts submissions from within and across subject domains such as those represented within the broad thematic areas below: Mathematical and Physical Sciences; Environmental Sciences; Medical and Biological Sciences; Humanities, Arts and Social Sciences. Originating from these broad thematic areas, the journal also welcomes submissions of software that works in cross cutting thematic areas, such as citizen science, cybersecurity, digital economy, energy, global resource stewardship, health and wellbeing, etcetera. SoftwareX specifically aims to accept submissions representing domain-independent software that may impact more than one research domain.
