Re: [TRNSYS-users] Parametric study



Patricia,

  Once you open the *.dck in TRNEdit, you can just change the block that reads:

EQUATIONS 2
AColl = 4.0
DHWDailyLoad = 200

to

CONSTANTS 2
AColl = 4.0
DHWDailyLoad = 200

While the TRNSYS engine and the parametric table part of TRNEdit make a distinction between CONSTANTS and EQUATIONS the Studio does not.

The access violation error is (I think) an old bug that has been fixed. I would recommend you contact your distributor to make sure that you are using the latest version.

kind regards,

 David

Hi,

 

My aim is to implement  a parametric study. My first question is:

What  is the difference between implementing in the Simulation studio  -> Calculate -> Parametric Study and in TRNEdit?

 

I have tried to  implement it  using TRNEdit according to the instruction in the Manual.

I have followed the example in the library  and I have a questions regarding the definitions of the Constants

 

Which I figured out that it comes from the file .tpf

 

 

When I  tried to implement it in a similar way I don’t get in .dck file the definition of the parameters of interest as Constants. They come as “equations”.

 

Did I miss any step in the preparation of the .dck file?

 

When I tried to run my file I  get and “access violation error”.

 

 

Thanks in advance,

/Patricia
