2019.2 Release Notes – Hydraulics Library 4.11

Modelon Release 2019.2

Hydraulics Library v4.11 is part of Modelon’s 2019.2 release.

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

Improvements

  • In the model Hydraulics.Restrictions.Basic.Templates.OrificeInput:
    • Documentation has been added so the different ways to parametrize the orifice are described.
    • Common equation of the if-statement has been moved out of the statement.
    • Smooth operator has been substituted by a max operator in order to avoid generating event in some cases.
    • In addition, the derived parameters Amax and Dmax have been renamed respectively Anom and Dnom – to better refflect the fact that these are computed from nominal volume flow rate and pressure losses.
  • The RelativeStates component within Modelon.Mechanics.Translational.SingleRodDualStop and Modelon.Mechanics.Translational.SingleRodSingleStop is removed, as the relative states are already available in endStopA.
  • The examples were updated to use the World component from Modelon Base Library (Modelon.Mechanics.MultiBody.World).

Fixed Issues

  • In the model Hydraulics.Valves.Basic.MeteringOriTwo, the documentation was clarified in order to specifically state that it models a valve with grooves on the sleeve.
  • The Excavator experiment is now more consistent with the listed reference.
