  2. 2. Final NNR Garp3 Modelling and Simulation Workbench Release Jochem Liem, Floris Linnebank, Anders Bouwer and Bert Bredeweg (University of Amsterdam,September 2007) In the simulation results, remarks made by modellers The university of Amsterdam has released a on model ingredients are all gathered and shown innew version of the free Garp3 workbench for tooltips. This was a non-trivial task, since thequalitative modelling and simulation in the final month simulation engine uses a pure Prolog program codeof the project. This will be the final release of Garp3 representation compared to the object-orientedin the context of the NaturNet-Redime project. The model building environment. The end result is thatusability and functionality of Garp3 has come a long tooltips in the simulation results now integrateway since the start of the project. Initially, three remarks originating from model ingredient definitions,separate applications were needed to build ingredients in scenarios, and ingredients in multiplequalitative models (Homer), to simulate them (Garp), model fragments, and specify where they came from.and to visualise their results (VisiGarp).
