IMP3

The Integrated Modelling Project #3 on "Transport Code and Discharge Evolution" plays a central role in the Integrated Tokamak Modelling Task Force (ITM-TF): virtually all the other modelling projects will need information on the plasma state (densities, temperatures etc.) simulated by IMP3 modules; at the same time these modules require data from the other projects' modelling codes, e.g. auxiliary heating deposition profiles. The ultimate goal of the IMP3 activity, and the ITM-TF in general, is whole device modelling, i.e. integrating modelling of all the essential processes relevant for a fusion plasma. Within IMP3 itself the major challenge is to integrate modelling of different transport processes and regions of a fusion device. For instance the core transport needs to be coupled to the edge transport, which in its turn must be integrated with models for the thermal properties of targets etc. Moreover, the developed transport code interfaces must be adapted to incorporate the data structures that provide the necessary information, e.g. sources and sinks, simulated by codes from the other IMPs. In fact, models of different complexity and scope are needed for the ITM-TF, ranging from 0D modelling for fast routine assessments of various scenarios to 2D-3D models that integrate all the relevant regions of a fusion plasma.
