开发了优化工具和有限元求解器之间的通用接口。表现出一系列目标函数的能力。用于识别脊柱材料参数的详细应用。在GPL许可下共享的示例,请访问https://github.com/mengomarlene/opti4Abq。在肌肉骨骼应用的计算建模中,一个关键方面是确保模型能够捕获固有的群体变异性,而不仅仅是代表“平均”个体。考虑到这一点,开发和校准模型是建模方法可信度的关键。这通常需要校准复杂的模型,以便对一系列样本或患者进行3D实验和测量。大多数有限元(FE)软件的核心工具中没有嵌入这样的功能。本文介绍了一个通用的接口之间的有限元(FE)软件和优化工具,使一组有限元模型的实验数据范围内的校准。它是作为Python工具箱提供的,已经在Windows平台上进行了充分的测试和验证。该工具箱在三个案例研究中进行了测试,涉及脊柱组织的体外测试。
Versatile interface between optimisation tools and Finite Element solver developed. Capacity demonstrated for a range of objective functions. Applications detailed for the identification of material parameters in the spine. Toolbox shared under GPL license at https://github.com/mengomarlene/opti4Abq. In computational modelling of musculoskeletal applications, one of the critical aspects is ensuring that a model can capture intrinsic population variability and not only representative of a “mean” individual. Developing and calibrating models with this aspect in mind is key for the credibility of a modelling methodology. This often requires calibration of complex models with respect to 3D experiments and measurements on a range of specimens or patients. Most Finite Element (FE) software’s do not have such a capacity embedded in their core tools. This paper presents a versatile interface between Finite Element (FE) software and optimisation tools, enabling calibration of a group of FE models on a range of experimental data. It is provided as a Python toolbox which has been fully tested and verified on Windows platforms. The toolbox is tested in three case studies involving in vitro testing of spinal tissues.
