====== Init all Variables 3D ======
All variables except the wind speed will be calculated in the full [[3D model]] using the new wind field and using the initial conditions for the thermal stratification and surface temperatures. 

===== Possible Problems & Solution =====

==== Missing Convergence in the Turbulent Kinetic Energy (TKE) field ====
Under extreme conditions, the model may fail to initialize the TKE field. \\
In this case check if the start conditions are realistic (surface temperatures, wind speed,..). \\
Check if the start time of the model is ok. 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.
