[TRNSYS-users] Automatic calculation for several clients

[David BRADLEY]

Alain,
   I am not sure how familiar you are with the deck syntax but you can 
do this by making some edits in the *.dck file using TRNEdit.  When a 
Type references an external file, it does so using an integer that is a 
parameter for the component (Type9 in this case) and is also found in an 
ASSIGN statement that associates that integer with a file and path. It 
looks like:

ASSIGN c:\Trnsys17\MyProjects\DataFiles\File1.txt      30

1. Open your *.dck in TRNEdit and add an ASSIGN statement like the one 
above for each data file that you want to run.

ASSIGN "c:\Trnsys17\MyProjects\DataFiles\File1.txt"      30
ASSIGN "c:\Trnsys17\MyProjects\DataFiles\File3.txt"      31
ASSIGN "c:\Trnsys17\MyProjects\DataFiles\File4.txt"      32

2. Change the Type9 logical unit parameter to a string called "LU"

UNIT 2 TYPE 9     Type9g
*$UNIT_NAME Type9g
*$MODEL .\Utility\Data Readers\Generic Data Files\Expert Mode\Specified 
Format\Type9g.tmf
*$POSITION 335 212
*$LAYER Main #
PARAMETERS 10
2        ! 1 Mode
0        ! 2 Header Lines to Skip
1        ! 3 No. of values to read
1.0        ! 4 Time interval of data
1        ! 5 Interpolate or not
1.0        ! 6 Multiplication factor
0        ! 7 Addition factor
1        ! 8 Average or instantaneous value
LU        ! 9 Logical unit for input file
... etcetera

3. Write the lines:

CONSTANTS 1
LU = 30

in your input file

4. Create a parametric table with as many runs as you have data files 
and the variable "LU" in the table.

5. set the value of LU to the integers that you assigned to each of your 
data files.

Best,
  David
