"error: Neighbours cannot communicate." (Minimal working example Application)
In commit baacbeca I added the new LimitingADERDG application ApplicationExamples/Experiments/GridDemonstrator
where I test different limiter criteria.
In the submitted example, the code crashes after the first timestep with error: Neighbours cannot communicate.
