modelPressureSource
Prescribed pressure at port with unlimited mass
Extends from Physiolibrary.Fluid.Interfaces.CompositionSetup (Initial substances composition setup).
Information
Model has a vector of continuous Real input signals as pressures for vector of pressure-flow connectors.
Usage in tests: Set defaul volume>0 and try to set STEADY in instances to "false"!
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Initialization | |||
| Modelica.Units.SI.Pressure | pressure_start | system.p_ambient | Initial pressure |
| Modelica.Units.SI.Temperature | temperature_start (from CompositionSetup) | system.T_ambient | Initial temperature |
| Initialization of medium composition | |||
| Modelica.Units.SI.MassFraction[:] | massFractions_start (from CompositionSetup) | Medium.reference_X | * Masses of all base molecules. If size is nS-1 then last value is 1-sum(others). If size is nS then all values are scaled to sum==1. |
