GRILLIX simulation data for TCV-X21 divertor validation project This dataset contains simulation data from the GRILLIX high-performance edge simulation software. The simulation data is for the TCV-X21 divertor validation case. It contains two large-file types. These are stored separately from the main TCV-X21 repository, to reduce the repository size for the base validation repository. The first are "work files", which allow you to check the time-resolved dynamics of the GRILLIX TCV-X21 results. The second are "checkpoints", the complete simulation state at a single time-point (as well as input files), which might be helpful if you are starting new TCV-X21 simulations. To use these files, you can use the TCV-X21 processing routines. For more details about the project, please check the arXiv version, available at https://arxiv.org/abs/2109.01618
