在过去的十年中，许多新的模型降阶方法和算法被开发出来。工业和学术研究机构打算用他们自己的模型测试、验证、比较和使用这些新的有前途的MOR技术。因此，开发了一个MOR工具箱，将理论、算法和数值开发与面向最终用户的程序之间的差距缩小为非专家可用的程序，称为“弹性多体系统的模型降阶”（Morembs）。c++实现以及Matlab实现，包括直观的图形用户界面。可以从各种有限元程序中导入，并且可以将简化弹性体导出到各种程序中以模拟紧凑模型。在各种项目的过程中，在算法方面增加了许多改进。正如我们多年来所了解的那样，没有一种“最佳”的MOR方法。“最佳”MOR取决于环境，如边界条件、激发光谱、进一步的模型使用。该工具箱现在被用于固体力学、生物力学、车辆动力学、柔性结构控制或碰撞模拟等领域。在所有这些用例中，工具箱允许用户简化他们熟悉的建模和仿真环境。在预处理过程中，仅使用Morembs执行关键的MOR过程，这有助于比较各种MOR技术以找到最适合的MOR技术。
Many new promising model order reduction (MOR) methods and algorithms were developed during the last decade. Industry and academic research institutions intend to test, validate, compare, and use these new promising MOR techniques with their own models. Therefore, an MOR toolbox bridging the gap between theoretical, algorithmic, and numerical developments to an end-user-oriented program, usable by non-experts, was developed called ‘Model Order Reduction of Elastic Multibody Systems’ (Morembs). A C++ implementation as well as a Matlab implementation including an intuitive graphical user interface is available. Import from various FE programs is possible, and the reduced elastic bodies can be exported to a variety of programs to simulate the compact models. In the course of the various projects, many improvements on the algorithmic side were added. As we learned over the years, there is not one ‘optimal’ MOR method. ‘Optimal’ MOR depends on circumstances, like boundary conditions, excitation spectra, further model usage. The toolbox is now used, e.g., in solid mechanics, biomechanics, vehicle dynamics, control of flexible structures, or crash simulations. In all these use cases, the toolbox allows the user to facilitate their well-known modeling and simulation environment. Only the critical MOR process during preprocessing is performed with Morembs, which helps to compare the various MOR techniques to find the most suited one.
