Re: [TRNSYS-users] Parametric runs



Dear Mohit,

You can run a parametric table in TRNEDit. You would have to make the following modifications to your file:

1. Add a constant definition:

CONSTANTS 1
LU_TMY2 = 35

2. Duplicate the statement 'Assign' for all the locations that you want to study. For example,
ASSIGN ".\Weather\US-TMY2\US-WI-Madison-14837.tm2" 35
ASSIGN ".\Weather\US-TMY2\US-AK-Anchorage-26451.tm2" 36
ASSIGN ".\Weather\US-TMY2\US-AK-Annette-25308.tm2" 37

3. In your data reader, look for the parameter that sets the 'logical unit number' of the weather data file. Replace the number with the constant LU_TMY2. For example, if you are using Type109, it would be the second parameter.


4. In TRNEdit., go to menu 'Parametrics' --> 'New table'. You will see that the constant LU_TMY2 is among the list of possible parameters to change. You have enter the values that you assigned in the statements ASSIGN; in the above example, you should enter 35, 36 and 37.

5. Run the table.


I am attaching a file based on the example 'Begin'. Please let me know if you have problems implementing this solution.
Best regards,

Diego

Hi all,
I have created a SDHW deck file (.dck). I was wondering if there was a
way i could run that file for all possible locations TMY2 at once and
not have to run the file for each location individually.

Thanks alot,
