AbstractSimulations of fusion plasma obtained in a Tokamak device can involve a wide range of physics phenomena occurring at different scales. Programming such a simulation is challenging and tends to increase the complexity of the code and its maintenance. Many approaches are trying to alleviate this issue by coupling several single scale components, the complexity being moved from the physics code to the coupling and execution platform. In this paper we are presenting the Integrated Plasma Simulator (IPS) platform, its advantages for running efficiently coupled simulations for different plasma physics use cases and are briefly comparing it to other platforms used in the fusion community.
