<p>Susanna,</p>
<p> 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:</p>
...<br>
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v1).b17
401<br>
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v2).b17
402<br>
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v3).b17
403<br>
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v4).b17
404<br>
ASSIGN c:\Trnsys17\MyProjects\BuildingParametric\building(v5).b17
405<br>
<br>
CONSTANTS 1<br>
LU_B17 = 401<br>
<br>
UNIT 1 TYPE 56<br>
PARAMETERS 3<br>
LU_B17 ! 1 Logical unit for building description file (.bui)<br>
0 ! 2 Star network calculation switch<br>
0.5 ! 3 Weighting factor for operative temperature<br>
...<br>
<br>
you'd then add LU_B17 to your parametric table and set the values to
401 through 405.<br>
kind regards,<br>
