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 On 12/13/2016 08:23, Susanna Magli via
