CO-LaN is conducting interoperability tests between software products implementing CAPE-OPEN interfaces. These tests are performed on computers owned by CO-LaN. Software vendors provide CO-LaN with free-of-charge licenses and in return receive reports on the tests performed, enabling them to improve if needed their implementation of CAPE-OPEN interfaces.

ProSim SA has renewed till December 31, 2008 its commitment to such a test program by providing CO-LaN with one license of ProSim Plus and one license of Simulis Thermodynamics. CO-LaN thanks ProSim SA for this arrangement.
