Ines,<br>
I would be surprised if you need to change CONTAM files
mid-simulation. If you are using the Type98 coupling then you should
be able to control the opening factor for the various airflow paths
through additional inputs to the Type98 model. You can do the same
with the Type97 coupling (i.e. define controllable openings).
Instructions for doing so can be found in the Type97 section of the
04-MathematicalReference manual.<br>
<br>
It is possible to select different building files for a parametric
run but in order to do so, you need to edit the *.dck manually and
add some lines. The basic steps are as follows:<br>
1. make sure that all of your building files have exactly the same
inputs and outputs.<br>
2. open the *.dck in TRNEdit and find the line that assigns the
*.b17 file an integer value. It should look something like: ASSIGN
"MyBuilding_v1.b17" 31<br>
3. copy that line and paste it as many times as you have different
versions of the *.b17. Change the name of the *.b17 file each time
and choose a unique integer each time. You might end up with:<br>
<br>
ASSIGN "MyBuilding_v1.b17" 31<br>
ASSIGN "MyBuilding_v2.b17" 32<br>
ASSIGN "MyBuilding_v.3b17" 33<br>
ASSIGN "MyBuilding_v.4b17" 34<br>
<br>
NOTE: it is very important that you search through the *.dck and
make sure that there are no other ASSIGN statements that refer to
the same integers that you've chosen. You can choose any integer
between 11 and 999. Make certain they're unique or else you'll get a
fatal error when you run the simulation.<br>
<br>
4. Find the definition of Type56, specifically the definition of
Type56's first parameter. It might look like:<br>
<br>
...<br>
PARAMETERS 3<br>
31 ! 1 Logical unit for building description file (.bui)<br>
...<br>
<br>
change it to look like:<br>
<br>
...<br>
PARAMETERS 3<br>
BLDG_LU ! 1 Logical unit for building description file (.bui)<br>
...<br>
<br>
5. add the following lines to the *.dck<br>
<br>
CONSTANTS 1<br>
BLDG_LU = 31<br>
<br>
6. Choose "new table" from the "Parametrics" menu and select the
BLDG_LU variable. Enter the values of the integers you chose in step
3 in each row of the parametric table.<br>
<br>

Subject: Re: [TRNSYS-users] Using multiple external files at
different periods<br>
<br>
Ines,<br>
How to do this depends a bit on what the external files
are being used for. Are you reading the data using a Type9
or is it that you want to use different performance data for
a given component at some times of the year?<br>
kind regards,<br>

I am asking if there is a way to run a deck using multiple external files at different periods of the year.
