If you are rather interested in
using a given model that is already in Capsis, you would be redirected to the 'Capsis modeller' who already integrated his own model in the platform, he can be found on the Capsis web site, on the page referencing all the projects, he knows a procedure to build an installer with Capsis core + his model (without the models of the other partners) and can distribute it to anyone (e.g. you):
