The model should begin the simulation in the night or in the morning hours of the simulated day. + + If nothing helps, let the model run and wait for the first output (even the PANIC DUMP). Open it in LEONARDO (it's a set of file like the normal output) and look where the problem is located. Normally the point of trouble is quite visible due to unrealistic high and/or low values.\\ + Consider to modify this area slightly.\\ + Sometimes it helps to change the inflow direction of the wind a few degrees. This does not actually effect the model results but might help in case of numerical problems.
