+ | ====== 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, | ||
+ | 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. | ||
