.ThermoPower.Gas.Utility.ClosedSystemInit .ThermoPower.Gas.Utility.ClosedSystemInitThis component can be used for the steady-state initialization of closed-system where all components have steady-state initial conditions. Without this component such systems would give rise to undetermined initial conditions, i.e., the amount of fluid and the initial pressures in the system would be unspecified.
Connect the component to one point of the system. If
initEquationFromInput = false, the system is
initialized with pressure equal to pstart at the
connection point.
It is possible to use a generic initial equation instead of
p = pstart, e.g., to set the initial charge of a
refrigeration circuit, by setting initEquationFromInput =
true and connecting to the input the output of a Modelica.Blocks.Sources.RealExpression
component, containing the residual of the initial equation. In this
case, if useHomotopy = true, the simplified initial
equation is (p - pstart)/pstart = 0. To ensure a
smooth homotopy transformation, it is recommended to write the
residual in normalized form, i.e., with values have the order of
magnitude of one, as for the simplified equation.
