Thread-topic: [TRNSYS-users] problem: undefined variable in equation - full simulation-file doesn't work

Dear Florian,

as far as I can see, you didn’t define Q_h. You should add an Equation, e.g. Q_h=[Logical unit,Output-number]. Which type calculates your Q_h?

I hope this helps.

Best regards

Margarethe

Betreff: [TRNSYS-users] problem: undefined variable in equation - full simulation-file doesn't work

Dear community,

with help from a other student i build a full simulation with different types but it doesn't work. There is this following error:

* EQUATIONS "Einheiten"
*

EQUATIONS 2
Q_h_SI = Q_h/1000*Heizsignal

*** Fatal Error at time : 0.000000
Generated by Unit : Not applicable or not available
Generated by Type : Not applicable or not available
TRNSYS Message 20 : The referenced variable used in this equation has not been defined in the TRNSYS input file. The equation begins with the string in "reported information"
Reported information : Q_H_SI = Q_H/1000*HE

Where i can define this called "variable"? I've added my simulation-studio file (use TRNSYS16)

Thank you in Advance!

Florian
