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

[David BRADLEY via TRNSYS-users]

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
