[TRNSYS-users] Branch function implementation using equations

[Ana Delgado]

Hello,

I have an input variable that changes over time. The most correct way to characterize it is to use a branch function. I wanted to use the equations feature but it is giving me lots of errors. Using programming language, my variable changes like this:

If -57 < x < -30

Y1=8E-5x^2-0.0024+0.2385
End IF

If -30< x<-15
Y2=0.0001x^2+0.0028x+0.3494
End if

If -15< x<-5
Y3=-0.0001x^2-0.004x+0.3058
End if

Do you have any tip on how to do it on TRNSYS? Also it’s not mandatory to use equations.

Thank you in advance,
Kind Regards,
