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.

• Initial Data Setup
• Memory Setup
• Creating Directory Tree

• Read SOILS.DAT/PROFILS.DAT
• Read SOURCES.DAT + Local Sources
• Read PLANTS.DAT + Local Database

• Read Area Input File
• Collect Receptors, Remove invalid Receptors

• Link PROFILS.DAT to SOILS.DAT
• Link Area Input File to PROFILS.DAT

• Create Grid
• Prepare Output Files
