Hopsan – 流体系统的免费模拟环境

这是 一个免费的开源模拟和建模应用程序，用于 机电系统 和流体能量 可用于 Gnu/Linux 和 Windows。

Hopsan 是一个开源的多域系统仿真工具。 一直 由林雪平大学机电和流体系统部门开发，它是在 Apache 2.0 版许可下发布的。

最初这个程序是为模拟流体能量系统而开发的，但也 已经扩展，支持其他领域，如电气、机械、飞行动力学和车辆动力. Hopsan 使用双向延迟线（或 TLM 传输线元件) 来连接物理组件模型，但它还支持使用常用数学函数和运算符进行信号流建模。

Hopsan is an open-source multi-domain system simulation tool developed at the division of Fluid and Mechatronic Systems at Linköping University. Hopsan is developed by a group of coworkers at the division, all with varying levels of knowledge in programming, modeling, simulation and hydraulics.

Development first began in the late 1970’s, and it has played an important role in education and research projects and over time.

In 2009, development began of a new object-oriented simulation platform written in C++. There is a strong focus on multi-core support and tool interoperability. This version is available under the GPL open source license.

Hopsan was the first system simulation tool with built-in support for multi-core simulation. It is also the only simulation software that is built around the transmission line modelling (TLM) technique (or bi-directional delay lines). With this method, models can be automatically partitioned by introducing physically motivated time delays between components. Each part of the model can then be solved independently during each time step. This improves simulation performance, numerical robustness and model scalability makes the simulation very robust and fast, and provides a natural mechanism for parallel simulation.

Feautures include

• Multi-core support for faster simulations
• Model export/import using Functional Mock-Up Interface (FMI)
