Dear Henk,<br>
<br>
You could define the parameters You want to vary as equations in the
control cards with free values (equations=xxx; cp_fluid=4.91;
m_fluid=... ...). Give the type these placeholders as parameters (first
You have to set the unit to "string", otherwise the type won't accept a
combination of characters instead of numbers). Then set up a table in
TRNEDIT with the different combinations of values for these parameters.
That's how I simulated a large amount of collector-area, -orientation,
storage-capacity and backup combinations.<br>
<br>
You will recieve a large amount of output files You have to deal with.
I did this with a combination of windows batch file and excel, but i
think an awk-script would be more elegant...<br>
<br>
Hope i was a help.<br>
<br>
Best regards,<br>
Jochen<br>

<pre wrap="">Hi,
In several schema's, e.g. the solar heater, a liquid is used with its properties such as specific heat and mass. Now I want to store that properties in a sort of database, so that I can easily use them in different schemas, simulate different liquids in the same shema, etc.
Has anyone experience herewith? Is there a sort of database technique in TRNSYS?
Thanks for suggestions,
Henk
