The PCIAssist software is freely available for research use, and is currently limited to demonstration purposes. If you are interested in developing a coupled model, please contact us. PCIAssist is available for Windows and Mac OS X and requires only that the Java Runtime 5.0 software is installed (free download). There is no installer or setup required to use the software, simply unzip the downloaded file to your desktop and double-click the PCIAssist.jar file to run PCIAssist. You must agree to the research-only license before downloading.
