Information
In an eighth step, a filter is added for the compressor outlet pressure to avoid forming an implicit nonlinear equation. The introduced state also requires appropriate start values. Additionally, the time integration may be implicit and could solve nonlinear equations as well.
The filter time constant should be chosen sufficiently small to avoid interfering with the pressure ramp.
Further documentation is available in the AirCycle package.
