The second phase of the RAMI initiative is now closed. RAMI-2 was constructed around two components: The first being a repetition of all test cases in direct mode that were already part of RAMI-1, offering the possibility to re-evaluate models that have been upgraded since, as well as to accomodate newcomers. The second component of RAMI-2 was designed to test the performance of three-dimensional models in significantly heterogeneous environments. The design of this latter series of experiments followed the conclusions and recommendations of RAMI-1.

Access to descriptions of the various experiments and measurements, as well as the corresponding model simulations and results statistics can be obtained through the links provided below.

Information on the participating RT models and scientists of the second phase of the RAMI initiative can be found through the 'Models' and 'Participants' links, that are located within the navigation bar at the top of this page, respectively.


The long term effort implied by the organization of such an intercomparison campaign can only be sustained through team work. The overall scientific leadership for this second RAMI exercise was provided by Bernard Pinty, with the active participation of Jean-Luc Widlowski, who created the images and provided the detailed specifications of the protocols for the new heterogeneous experiments.Phase 2 was initially also hosted on the ENAMORS web site maintained by Michel Verstraete. Malcolm Taberner designed and ran the computer codes necessary to analyze the results and generate the graphical output provided here.
