BESLE: Boundary element software for 3D linear elasticity

BESLE is the first available parallel open-source code to analyse the mechanical behaviour of heterogeneous materials using the boundary element method (BEM) in 3D and in both an elastostatic and elastodynamic setting. Unlike all the other codes that are presently available, the software presented here is capable of simulating both isotropic and anisotropic materials comprised of single or multiple domains. Furthermore, the user-interface has been designed to provide a convenient way for configuring simulations involving many complex material constituents. Results are described by the displacement and traction fields, also, the stress and strain tensors are available for post-processing. BESLE is largely implemented in Fortran-MPI, but some of the sub-packages are based on other languages such as C and C++, and as such a the software is best used on a multi-core architecture where the parallelisation can be fully exploited. The main features and functionality of BESLE are presented here, and the User's Guide, available from the repository listed below, gives further details and outlines how users can carry out bespoke simulations.

BESLE 是首个可用的并行开源代码，用于分析异质材料在三维空间中的机械行为，采用边界元法（BEM）在弹性和动力环境下的应用。与目前所有其他代码不同，本软件能够模拟由单域或多域组成的各向同性和各向异性材料。此外，用户界面被设计成提供一种便捷的方式，用于配置包含众多复杂材料组分的模拟。结果通过位移和牵引场进行描述，同时，应力张量和应变张量也适用于后处理。BESLE 主要采用 Fortran-MPI 实现，但某些子包基于其他语言，如 C 和 C++，因此该软件在多核架构上使用最佳，能够充分利用并行化能力。以下是 BESLE 的主要功能和特性，用户指南（可通过以下列出的存储库获取）提供了更多细节，并概述了用户如何进行定制化模拟。
