3.19Data Processing Heirachy

The order in which data are read and processed is provided below. The list is not exhaustive, but provides a guide to the data input process.

1. 
   Read parameters (variables, options, etc) from .tcf file.
   
2. 
   Read any material data from .tmf file.
   
3. 
   Open .tgc file:
   
   1. 
      Locate and orientate 2D grids.
      
   2. 
      Allocate memory for 2D domains.
      
4. 
   Identify any 2d_fc flow constrictions (FC).
   
5. 
   Identify any 2d_po (PO) time-series output.
   
6. 
   Identify any 2d_lp (LP) time-series output.
   
7. 
   Open .tbc file:
   
   1. 
      Read through 2D boundary conditions.
      
   2. 
      Allocate memory for 2D boundary conditions.
      
8. 
   Return to .tgc file:
   
   1. 
      Process instructions in .tgc file to build 2D domains.
      
9. 
   Finish reading information from .tcf file, including:
   
   1. 
      Read any 2d_fc flow constrictions (FC).
      
   2. 
      Read any 2d_po (PO) time-series output.
      
   3. 
      Read any 2d_lp (LP) time-series output.
      
10. 
    Open .ecf file (if 2D/1D model):
    
    1. 
       Read parameters (variables, options, etc) from .ecf file.
       
    2. 
       Read all 1D node information from all 1d_nwk layers.
       
    3.

    4. 
       Read all table link information from all 1d_ta layers.
       
    5. 
       Read all 1D channel information from all 1d_nwk layers.
       
       1. 
          Any channel cross-section information from 1d_ta table links or external sources (eg. MIKE 11 .txt or ISIS .pro files) are processed.
          
       2. 
          Any bridge loss coefficient tables from 1d_ta table links are processed.
          
       3. 
          Parameters for any culverts or weirs written to temporary file (_cnch.tmp).
          
    6. 
       Read all table link information for 1D node storages (NA tables) from all 1d_ta layers.
       
    7. 
       Process any initial water level commands (eg. Read 1d_iwl layers).
       
    8. 
       Read any fixed field CS tables.
       
    9. 
       Read any fixed field NA tables.
       
    10. 
        Allocate memory for topography.
        
    11. 
        Read any boundary condition data and allocate memory.
        
    12. 
        Read any structure parameters and allocate memory.
        
    13. 
        Repeat above and retain information in memory.
        
    14. 
        Carry out pre-processing and checking tasks.
        
11. 
    Read 2D boundary conditions into memory and write 2d_bc check file.
    
12. 
    Carry out pre-processing and check tasks:
