Re: [TRNSYS-users] jEPlus for TRNSYS parametrics

Hi Bjoern,

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, ...}".

Here is quick video of how to use jEPlus (http://www.youtube.com/watch?feature=player_embedded&v=9v8k52IyvV4). Again it is for E+ rather than TRNSYS; but the principle is the same.

Cheers,

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.

Hi all,

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.

Regards,

Yi
