Adnan,
There is also an AND() function available. The function returns a 1 if both the first and second arguments are 1. For instance:
zz = AND(x,y)
zz will be 1 if both x and y are 1.
There is a full list of functions in the 06-TRNEdit.pdf manual (section 6.3.9.1)
kind regards,
David

Thanks Jeff,
The detail is like that...
Case 1EQUATION EditorWeather data --------------------------------- Solar radiation Win_id_1 = 0Win_id_2 = 1
Win id = GT(Solar_R,100)*Win_ID_1+(LT(Solar_R,100))*Win_ID_2 ----------------------------------------------------------Type 56 input (for controlling Window)
Case 2
EQUATION EditorWin_id_1Weather data----------------------------------- Temp Win_id_2
Win id = GT(Temp,20)*Win_ID_1+(LT(Temp,20))*Win_ID_2
BOTH CASE 1 AND 2 WORKS FINE.
Case 3now case three i want to control both temp and solar radiation combine and need to get one output for TYPE 56
Like when temp > 20 and solar radiation > 100 output should be 0.. and when temp < 20 and solar radiation < 100 out put should be 1
Hope this explanation will help.Thank you very much for looking into my problem.
RegardsAdnan

Adnan,
You didn’t give us enough information to be able to write the equations. What happens when the radiation is high but the temperature is low? And the opposite condition? But we can set it up in a basic format for you to edit:
Equations 3SolarHigh = GT(Solar_R,100)TempHigh = GT(Temp,100)Win_ID = SolarHigh*TempHigh*ID1+SolarHigh*(1-TempHigh)* ID2+(1-SolarHigh)*TempHigh*ID3+(1-SolarHigh)*(1-TempHigh)* ID4
Basically set up your equation to account for all 4 outcomes. Just fill in the correct ID in the equation above and you should be good.

Hello everyone,
i am using simulation studio's equation editor, two equations with different parameters set values separately, and they work fine now i want to control two parameters together with two equation combine how i can do this
my equations are e.g
1) win_id_input = INT(GT(Solar_R,100)*Win_ID_1+(LT(Solar_R,100))*Win_ID_2
2) win_id_input = INT(GT(temp,100)*Win_ID_1+(LT(temp,100))*Win_ID_2
need one out put both conditions together,
Thanks in advance
