 * A new model is declared with the Model keyword and a name.
 * A model can have several sections presented above:
 *#
FlowSheet CustomFlowSheet

        #*
         * In the PARAMETERS section we can define the constants of the
         * model.
         * A parameter will never be the result of the simulation its value
         * need to be specified by the user.
         *#
        PARAMETERS
        V as volume(Brief="The model volume");
        A as area(Brief="Cross section area");

        #*
         * In the VARIABLE section we declare the variables of the model.
         * The values of the variables will be calculated by the system
         * in order to respect the model equations.
         *#
        VARIABLES
        h as length(Brief="The level");
        
        #*
         * In the EQUATIONS section we declare equality expressions involving
         * the any previously declared parameter or variable.
         * The equations will be used to determine the value of the variables.
         *#
        EQUATIONS
        A * h = V;

        #*
         * Additionally, in the case of dynamic models we can declare initial
         * conditions exactly as in the EQUATIONS section.
         * Equations declared on the INITIAL section will be used to determine
         * the initial condition of dynamic models.
