====== Overview Model Run ======
The following section gives an overview of the different steps executed in the model. It is a good help to determinate the locations of errors and problems in the model run.

===== Technical Model Start =====
 
=== Initial Work ===
  * [[Initial Data Setup]]
  * [[Memory Setup]]
  * [[Creating Directory Tree]]

=== Database Setup ===
  * [[Read SOILS.DAT/PROFILS.DAT]]
  * [[Read SOURCES.DAT + local sources]]
  * [[Read PLANTS.DAT + local plants]]

=== Simulation Files Setup ===
  * [[Read Area Input File]]
  * [[collect receptors|Collect Receptors, Remove invalid Receptors]]

=== Database Work ===
  * [[Link PROFILS.DAT to SOILS.DAT]]
  * [[Link Area Input File to PROFILS.DAT]]

=== Other Things ===
  * [[Create Grid]]
  * [[Prepare Output Files]]
[Check-only runs end here]

=== Calculation of Other Required Data ===
  * [[Calculation of other required data|Max Radiation at Noon]]
  * [[Calculation of other required data|SOR Coefficients]]
  * [[Calculation of other required data|Wind Speed Model Top]]

===== Initialisation =====
  * [[init 1d model|Init 1D-Model (all Data)]]
  * Init 3D-Model
    * [[Initial Diastrophy]]
    * [[DEM Properties]]
    * [[Initial Values 3D]]
    * [[Initial Exchange Coefficients]]
    * [[Wind Field Diastrophy]]
    * [[init all values 3d except wind|Init all Variables 3D except Wind]]
    * [[Calculate Wind Field for 10 Sec]]

===== Main loop =====
  * [[set main time step|Set Main Time Step according to Solar Height]]
  * [[Update DEM Diastrophy]]
  * [[Update Radiative Fluxes]]
  * [[Calculate or Update Wind Field]]
  * Update Model
    * [[1D and 3D Atmospheric Data]]
    *  [[Soil Model - Temperature and Water]]
    *  [[Surfaces - Temperature and Humidity]]
  * [[Update Plant Physiology]]
  * [[Update Sources Emissions]]
  * [[Write Output Files]] (Repeat Loop until End Time)
