[TRNSYS-users] TESS tank Type 534 and Genopt

Bishan,

   Unfortunately GenOpt cannot access anything but the *.dck file. What 
you'll need to do is to use the Type534 proforma that does not use an 
external file but which instead defines all the parameters directly in 
the input file. There are a few versions of that Type534 proforma 
available in the direct access tool already. If you do not see the 
configuration you need (perhaps yours has more heat exchangers or a 
different kind of heat exchanger) then I can make one for you.

kind regards,

  David
