[TRNSYS-users] TRNSYS and GENOPT

[George Kyriakarakos]

Dear all,

 

I have been using the combination of TRNSYS 16 with TRNOPT and GenOPT
successfully for a long time for the sizing of renewable energy sources
systems. All this time I usually had 2-8 variables for optimization. Today I
wanted to optimize a system with 11 variables. I can add the variables to
TRNOPT and then I can run GenOPT. The problem is that the cost function
gives a result always between 0 and 1, where it should give a much higher
number (the cost function is an equation in TRNSYS). If I modify the TRNOPT
file to optimize 9 variables, leaving the rest the same, the cost function
is then calculated and depicted in GenOPT window correctly. If I add one
more variable then the problem occurs.

Has anyone else come across this problem? Is there any workaround? 

Thank you in advance for your answers,
