3.6.8 Hydraulics Library 
Hydraulics 4.1 is a major release with the following enhancements compared to 4.0. 
Examples of enhancements and improvements: 
•  The documentation is now improved throughout the library.  
o  The information section (Hydraulics.Information) has been updated. 
o  Each main-component have detailed documentation of usage, 
assumptions and extending classes.  
o  The information section for the templates (see e.g. Templates.TwoPort), 
displays what kind of equations that has to added to classes using this 
template. 
•  The package structure is improved throughout the library. Examples: 
o  A separate icons package (Utilities.Icons) is created with the most 
common Hydraulics Library Icons. 
o  Mechanical components and actuators are now located in the 
Utilities.Mechanics. 
o  The Visualizer package is located in Utilities.Visualizers. 
o  Many of the component and example names were abbreviations. Most 
of the names are now changed to the full name. 
o  Many components were old and deprecated. They are now placed in the 
package Utilities.Deprecated and will be removed after a year from the 
release when they were put in the deprecated package. These 
components are marked with a red cross and if they are used, a warning 
message will appear in the message log. If the user wants to keep using 
the component, it has to be copied to the local library. But they will no 
longer be supported by Modelon. 
o  Basic components now have a different look. A grey thick dashed line is 
placed around the components, to easily identify basic components. 
o  Pump and motor components are now merged and put into a new 
package: RotatyActuators.  
o  The new component RotaryActuator represents the following pump 
components: SimplePump, VariablePump, TabularPump and 
PumpWithLoss the following motor components: SimpleMotor and 
VariableMotor. 
o  The Sources package is now cleaned up and some components are 
merged. 
•   A few new components, examples and features have been added to the library. 
o  An example visualizing usage of a Modelon Base Library (MBL) Heat 
Exchanger, see Examples.ThermoHydraulicsGuide.HXTableEfficiency. 
This is possible using the new adaptor component 
Interfaces.ThermoFluidAdaptor. 
o  An example visualizing temperature rise in a closed system due to pump 
losses, see Examples.ThermoHydraulicsGuide.ClosedPumpCircuit.
