• Pressure Source (P)
• Flow Source (Q)
• Hydraulic Resistance (RHYD)
• Hydraulic Capacitance (CHYD)
• Hydraulic Inductance (LHYD)
Across and Through Quantity of the Fluidic Domain
Across Through Equation
Pressure [Pa] Flow Rate [m²/s²] qt () = K⋅p() t
The fluidic domain components appear in the Fluidic folder of Physical Domains in the «Basics»
tab. The folder provides fluidic basic components to model simple fluidic equivalent circuits.
The fluidic domain uses the pressure as across and the flow rate as through quantitate.
By default, components and wires of the fluidic domain are represented in green in the graphical
representation of the Schematic. Select SHEET>PROPERTIES to change the wire color of the
domain. You can only change the wire color. The symbol color is not affected by the setting.
Pressure Source
>>Basics>Physical Domains>Fluidic
The component represents an ideal pressure source which supplies the defined pressure differential
for an arbitrary flow rate. Within the dialog you can choose a constant or the timecontrolled
type.
Dialog Settings
� «Pressure Differential [Pa]»
The linear pressure source is selected. Common parameter type. Enter a numerical value, a
variable, or an expression in the text box or use the pin to connect a quantity.
� � «Use pin»
If the box is checked, the value is defined by the quantity connected to the pin, otherwise the
value in the text box is used.
� «Time Controlled»
The time-controlled pressure source is selected. In the list, select a time function and define
the corresponding parameters. See also “Using Time Functions” on page 275.
� In the list, select the sine, pulse, triangular, trapezoidal, saw-tooth rising, or saw-tooth falling
time function.

VALUE
The pressure is equivalent to the present value of the quantity specified in the text box. Usually
a constant value, a time function, or a variable are chosen, or the value is determined in
a state graph. All system quantities and variables can be combined with mathematical and
logical operators and constants.
