About jCpSim

jCpSim is an open source simulation environment for physiological processes (like ventilation) and their interaction with therapeutic measures (like ventilator therapy).

Running jCpSim

System Requirements

Java Runtime Environment (JRE), version 5.0 or later.

WebStart

To run a jCpSim simulation with Java Web Start (included in the Java Runtime Environment) you can click on one of the images below:

Volume controlled ventilation of simple lung model

Arterial line (under- and overdamping)

Or you can invoke Java Web Start fom the command line:
javaws http://www.jcpsim.org/jcpsim.jnlp

Download

You can also download the compiled software (jcpsim_0.2.02.jar) from SourceForge.

• (Double)clicking on jcpsim_0.2.02.jar will start the simulation on some operating systems.
• Or else you can start it from the command line:
  java -jar jcpsim_0.2.02.jar

News

2007-02-20

• First public release.
• Can be used for teaching simple respiratory mechanics.
• Much more is planned for the future ('real ventilators', more complex models, circulation, pharmacokinetics, ...) - depending on my spare time.

FAQ

How can i stay informed about new versions of jCpSim?

• If you run jCpSim via Web Start and are connected to the internet you will always have the latest version. If you are offline Web Start will load the version you did use the last time.
• You can subscribe to the jcpsim-announce mailing list (very low volume).
