Dynamic flowsheet simulation system for solid phase processes

在DFG优先项目“SPP 1679：相互连接的固体过程的动态模拟”的“中心项目：相互连接过程的动态模拟”项目中，开发了一个新的固体相过程动态流程图模拟系统。所设计的建模框架名为Dyssol，能够模拟固体过程工程领域复杂过程结构的瞬态行为。它采用波形松弛法，辅以收敛法和外推法进行快速动态计算。使用变换矩阵的方法可以适当地计算固相的多维相互依赖的分布参数。由于其特点，Dyssol系统不局限于一定的范围，而普遍适用于各种动态和稳态过程。虽然该建模系统在SPP 1679的范围内得到了验证，并且功能齐全，但它被设计为研究软件，依赖于开发人员与最终用户的密切互动。因此，Dyssol不能完全适应作为一个免费的、公开可用的、开源的应用程序的可持续使用。本提案中提出的项目的主要目标是为社区提供一个独特的开源系统，用于颗粒材料的动态流程模拟，可用于固体过程工程的广泛领域的研究和教育。为实现这一目标，计划解决以下任务：设计合适的用户界面以简化与系统的交互；用新的操作扩展模型库，使框架对广泛的研究人员和工程师更具吸引力和实用性；提供更容易和更灵活的方法，以新模型扩展系统；改善系统性能；提供程序代码的稳定性、可维护性和可扩展性；为系统的各个方面制定全面的文件；组织方便的公开访问源代码、二进制包和文档。

Within the project “Central project: Dynamic simulation of interconnected processes” of the DFG priority programme “SPP 1679: Dynamic simulation of interconnected solids processes” a new dynamic flowsheet simulation system for solid phase processes has been developed. The designed modelling framework, named Dyssol, is able to simulate transient behaviour of complex process structures in the area of solids process engineering. It applies waveform relaxation method, supplemented by convergence and extrapolation methods for rapid dynamic calculations. The used approach with transformation matrices allows proper calculation of multidimensional interdependent distributed parameters of the solid phase. Due to its features, the Dyssol system is not limited to a certain scope, but is generally applicable for a variety of dynamic and steady-state processes. Although the modelling system is validated and fully functional in the scope of the SPP 1679, it was designed as research software, counting upon the close interaction of developers with end users. Therefore, Dyssol is not fully adapted for sustainable use as a free, publicly available, open source application.The main objective of the project presented in this proposal is to provide the community with a unique open source system for dynamic flowsheet simulation of granular materials, which can be used for research and education in a wide range of areas of solids process engineering. To achieve this goal, it is planned to solve such tasks as: design a suitable user interface to simplify interaction with the system; extend the library of models with new operations to make the framework more attractive and useful for a wide range of researchers and engineers; provide easier and more flexible ways to expand the system with new models; improve system performance; provide stability, maintainability and extensibility of program code; develop comprehensive documentation for all aspects of the system; organize easy public access to the source code, binary packages and documentation.
