[TRNSYS-users] Parametric analysis with trnEdit - modify wall type

[Dr Yi Zhang via TRNSYS-users]

Why not try jEPlus for TRNSYS: http://www.jeplus.org/wiki/doku.php?id=docs:manual_1_7_project#trnsys_parametrics

Once set up, it will save you a lot of hassle managing those individual model files.

Susanna,

  The way that I have done this in the past is to make a copy of the *.b17 file for each parametric run that you want to do. Each one will have a different value of the thickness and a different name. In TRNEdit you'll then replicate the line that assigns the the *.b17 file name to a logical unit number (which is used as a Type56 parameter). You can then set the parameter / logical unit number as a constant and give a different value for each run of your parametric table. Your *.dck might have a section that looks like:

...
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v1).b17  401
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v2).b17  402
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v3).b17  403
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v4).b17  404
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v5).b17  405

CONSTANTS 1
LU_B17 = 401

UNIT 1 TYPE 56
PARAMETERS 3
LU_B17        ! 1 Logical unit for building description file (.bui)
0                ! 2 Star network calculation switch
0.5        ! 3 Weighting factor for operative temperature
...

you'd then add LU_B17 to your parametric table and set the values to 401 through 405.
kind regards,
 David

​Dear all,

I was wondering whether is it possible to run parametric simulations with TrnEdit varying the wall type (thickness of layers) or some layers properties.

Thank you

Susanna
