[TRNSYS-users] TRNSYS control cards

[Jeff Thornton]

Makram,

You can use an INCLUDE file.  Details can be found in the documentation.  The include file must also follow the TRNSYS requirements on structure.

So it may look like:
EQUATIONS 3
Tstart = 0
Tstop = 8760
Tstep = 0.05

Then these variable names appear in your control cards.  You could also put your control cards in an include file but then you have to edit the input file manually.
