* Model with some variables to be calculate further.

*#
Model CalcBasic
        PARAMETERS
ext NoComps as Integer;
        VARIABLES
        T    as temperature;
        P    as pressure;
        z(NoComps) as fraction;
        
        r1 as Real(Unit="K*K");
        r2 as Real(Unit="atm*K");
        r3 as Real;
end

#*************************************************
* Model with a CalcObject for the calculations
*
*#
Model Calc as CalcBasic
        PARAMETERS
ext     obj as CalcObject;

        EQUATIONS
        r1 = obj.method1(T, P);
        r2 = obj.method2(T, P);
        r3 = obj.method3(z);
end


#****************************************************
* Same as above but with the calculations
* done by equations instead of external routines.
* The results should be the same.
*#
Model Calc2 as CalcBasic
        EQUATIONS
        r1 = T^2;
        r2 = T*P;
        r3 = sum(z);
end

#*******************************************************
* Checking if the results are the same for both
* models (external calculations and explict equations).
*
* NOTE: IN ORDER TO RUN THIS EXAMPLE YOU NEED TO COMPILE
* THE FILE calcsample.cpp IN YOUR INTERFACE DIRECTORY
