Bertrand,<br>
The basic idea is that you have to open your simulation in TRNEdit
and select "New Table" from the Parametrics menu. TRNSED will
scan through your input file and find all CONSTANTS statements then allow
you to select which CONSTANTS are going to be parametrized in the table.
The concept of CONSTANTS is a little confusing sometimes for users most
familiar with the Studio but a CONSTANT is simply a simple
equation. If you have created a simple equation in your Studio project
that sets the value of a constant (called MyVariable in this example),
the Studio will have written:<br><br>
EQUATIONS 1<br>
MyVariable = 45<br><br>
in your input file. You would need to replace that in TRNEdit
with:<br><br>
CONSTANTS 1<br>
MyVariable = 45 <br><br>
before TRNEdit would realize that the variable could be
parametrized.<br><br>
Once you have created the table, you select "Run Table" from
the TRNSYS menu and TRNSYS will run repeatedly with all of the
combinations of variables in your table. The other thing to keep in mind
is that you should either set all of your printers to "append
mode" (one of the parameters) or you should make sure that all of
your output files have the same name as your input file (*.dck).
When running a parametric table, TRNEdit automatically duplicates all
output files that have the same name as the input file and it overwrites
any output file that does not. By setting printers to "append"
though, you can avoid the overwrite.<br>

Thanks to Adrien and David for the help they gave me for type 55.<br>
<br>
I would klike to know how to perform parametric studies. I red the
manual, but i don't understand very well how i should proceed. i will be
grateful for any help.<br>
