EXCELLERAT P2 D2.16 Report on the OpenFoam/Elmer Application Use Case

This document summarises the progress made in the OpenFoam/Elmer application use case (UC) FA-1 by University of Ljubljana (UL). We present the objectives of the use case and the development of the use case workflow in detail. The introduction explains the purpose and extent of the use case with respect to research in magnetically confined nuclear fusion. Then, the objectives of the use case are explained and its aim with respect to the EXCELLERAT P2 work is discussed. In section 3 the workflow is presented in more detail, explaining individual simulation steps needed to achieve the desired output of the use case. In sections 4 and 5 the current progress and next steps are presented. The progress achieved so far is presented with focus on a small-scale case and its role as a basis for large scale simulations. These are outlined in the conclusion section with the work layout for the future. The status of algorithmic optimisation is also presented with focus on parallelisation and storing data to binary files using the HDF5 file format.
