[TRNSYS-users] Regarding external input files

[Diego A. Arias]

Hi Mohammad,

I am not sure if I understood your question.  I have used a different 
approach when I want to use an external program to set the values of 
some parameters in a simulation.  You may know that you can use a nested 
input file in TRNSYS.  This is done with the instruction 'INCLUDE 
xxx.yyy', where xxx.yyy is the name of a text file with the additional 
instructions (please refer to Volume 7, section 7.6.17 The INCLUDE 
statement).

The external program should write a text file with the names and values 
of some variables that you will use as parameters in your simulation. 
For example, the contents of the file 'mytextfile.txt' can be:

CONSTANTS  2
VAR_1  =    0.3
VAR_2  =    0.2

In the Studio, go to control cards and add to the 'simulation cards':

INCLUDE mytextfile.txt

In your project, you can assign the values of these variables VAR_1 and 
VAR_2 to set the values of parameters that you want to change.

I will be happy to elaborate on this strategy if you need more information.
Best regards,

Diego

Dose any of these components (calling external program, Excel Type62, or parameter replacement, type70) do the job. Please any advice.
