 || Nested simulation || 02/01/2020 ||  || Simulations repeatedly hang / crash. The Lustre system in Berlin is still not full setup so that simulations repeatedly  hang / crash due to slow filesystem. ||
 || Nested simulation - initial run || 03/01/2020 ||  || Lustre filesystem issues seem to be solved for now. Initialization of the child has been changed. Child is now initialized via dynamic driver rather than via the coupler. This way all atmosphere grid points are initialized appropriately. The nested simulation is at t=30min. '''First estimate of duration''': in 12 h real time on 6720 cores we will simulate about 1 h. With 30 hrs simulation time (00:00:00 UTC - 06:00:00 UTC, next day), we will need about 30 restarts. Since the machine in Berlin starts to fill up now with other users, we are only be able to do 1 simulation at a day (optimistic scenario), so this will take at least one month. ||

+|| Nested simulation - restart run || 27/01/2020 ||  || After recurrent maintenance-related breaks on HLRN, restart simulation started again, restart data was read in, but simulation crashed with a HDF 5 error while reading the Netcdf input data. ||
