Hopsan is a free multi-domain system simulation tool developed at the division of Fluid and mechatronic systems at Linköping university. Features include:
- Multi-core support for faster simulations
- Model export/import using Functional Mock-Up Interface (FMI)
- Model export to Matlab/Simulink
- Plot data export to CSV, XML, Gnuplot & Matlab
- Creating models from Modelica and C++
- Interactive & replay animations
- Numerical optimization
- Sensitivity analysis
- Frequency-domain analysis
- Energy losses calculations
- Scripting using HCOM or Python
The TLM method uses wave characteristics to calculate pressure and flow, making it especially suitable for modeling of wave propagations. It also introduces physically motivated independences and time delays between components, which enables parallel execution by using multi-core technology. This can significantly increase simulation performance on computers with multiple core processors.
A Genuine Teamwork Project
Hopsan is developed by a group of coworkers at the division, all with varying levels of knowledge in programming, modelling, simulation and hydraulics.
A beta version of Hopsan is now available for download!
Developer News Feed
Also available in rss!
Snapshot releases from the development trunk of the next major Hopsan version (0.6) are now available to those who wish to assist in testing new functions while they are being developed.These releases should be considered UNSTABLE and may contain unfinished functions.Examples of two new major features are, 2d animation support and the possibility to convert double parameters into signal read ports.Windows releases as-well-as Debian package installers for the latest Ubuntu distributions are available.
Some Windows users may have noticed that the auto update function does not work. The reason for this is that Windows does not allow a program to store files in its own directory. The problem will hopefully be corrected before next release.
Hopsan 0.3.3 is now released. It contains important fixes of the dynamic behaviour for several mechanical components. It also fixes several crashes and other issues. Users of previous versions are recommended to update to this version. Note that Hopsan is still in the beta stage, and that many components are still not completely validated.
The Hopsan project is now using the Redmine project collaboration and bug tracking environment. This can for example be used for requesting features, reporting bugs and reading Hopsan-related news. Sign up today!
