Yes, if you replace in
the header of the type 56 unit in the dck file the LU number (parameter 1) with
the name of the constant, then it works.
For every dck file you
want to use you add an assign statement with an own LU number, in the
parametric table you refer to these LU numbers.

jEPlus for TRNSYS parametrics
…and
actually *.bui is called in the *.dck thanks to an ASSIGN statement.
Could
therefore parametrical runs work?
Thanks
a lot

Subject: RE: [TRNSYS-users] jEPlus
for TRNSYS parametrics
Sorry I don't recall if I responded to Saleh's
earlier question or not... Since I am not a TRNSYS user, José can correct me if
I get anything wrong.
jEPlus searches the specified search tags in the main
.DCK or .TRD files, as well as in any external files loaded by an INCLUDE or an
ASSIGN command. I don't know about the .BUI files; but if they are loaded
in the main .DCK file, you should be able to have parameters in them. To edit a
file other than the main .DCK, you will need to use a text editor...
To the second question, jEPlus processes output files
in CSV format only. Your model needs to write output in a .csv using the right
printer, and you tell jEPlus the files you want it to collect in the
"output file name(s)" field (I am renaming it to "printer
file name(s)"). So "trnsysout.csv" should be a printer name you
have in your .DCK model.
We are still working on the TRNSYS part of the users
manual. It should be ready in a few days' time.

Dear all,
Any news concerning the use
of jeplus for parametric changes in the *.bui (and not just in the *.dck) of a
trnsys project?
Thanks a lot

Think before you print
Thanks
for doing this great job!!!.
I
used the template file provided with GenOpt (folder is attached).
I
tried using this version with TRNSYS 16 and works pretty well and quick (24
parametric runs in less than a minute). Is it possible to add a browsing tab to
edit the building file (*.bui).
Although,
I could run the parametric files but no output was extracted. In my template
file, I normally extract output in a text file but jEPlus could not copy the
file or save it in any format. Is there a way to save the text file in the
folder file similar to input file. In addition, I can't find the
"trnsysout.csv" output file anywhere. Is that enabled in this
version?
I
should provide an example TRNSYS parametric project in the package; I will
do that in a couple of days. In the meantime, could you take a look at the E+
example? Just open the project in the example/ folder, and you will see how to
specify parameters. Unlike E+, the weather file in a TRNSYS model is
normal parameter. You just need to create a parameter and think of a search
string (e.g. "@@weather@@") to put in the place of the weather
file in the .DCK (or .TRD) file, and then specify the alt. values of the
parameter using syntax like "{weather1.txt, weather2.txt, ...}".

Hi
Yi,
I just had a short look at it and did not find an option to vary sets of
values, e.g. if I vary a location I need to specify the name of the weather
data file, the latitude, shift in solar time and possibly some other values. If
there is this option and I did not see it, please ignore my comment.

jEPlus
is an open source parametric tool for managing EnergyPlus simulations. Due
to popular demand, support for TRNSYS simulations has been added to the latest
version (jEPlus v1.3beta). Please visit http://www.iesd.dmu.ac.uk/jeplus/
for more details. Please note we are currently testing the new version; any
comments or suggestions will be much appreciated.
