MSL v3.2.3-2

Modelica Standard Library (MSL) version 3.2.3 build 3 with the following patches applied:

• To the model Modelica.Blocks.Examples.NoiseExamples.ActuatorWithNoise defined in Modelica/Blocks/
  package.mo a StateSelect.always is added for Controller.y1. With this patch dynamic state selection is avoided.
  See also the reported issue 2189 on the GitHub repository for Modelica Association (modelica#2189).
• The model Modelica.Electrical.Analog.Examples.SimpleTriacCircuit is patched to with a looser tolerance to
  improve numerical stability near certain event points.
• The state selection in Modelica.Magnetic.FluxTubes.Examples.Hysteresis.HysteresisModelComparison is
  patched to improve the numerical robustness, see issue 2248 on the GitHub repository for Modelica Association (modelica#2248).
• In Modelica.Fluid.Examples.TraceSubstances.RoomCO2WithControls the experiment tolerance is tightened to
  1e-008 instead of 1e-006 to avoid chattering.
• In Modelica.Magnetic.FluxTubes.Examples.Hysteresis.SinglePhaseTransformerWithHysteresis1 an initial
  equation has been added in order to fully specify the initial system, see issue 3409 on the GitHub repository
  for Modelica Association (modelica#3409).
• In Modelica.Electrical.Machines.Examples.AsynchronousInductionMachines.AIMC_InverterDrive the connection to ground has been relocated from the rectifier to the inductor in order to simplify the set of linear equations
  for proper state selection.
• In Modelica.Electrical.PowerConverters.Examples.ACDC.RectifierBridge2mPulse.DiodeBridge2mPulse the
  experiment tolerance is tightened to 3e-007 instead of 1e-006 to avoid infinite loops due to numerical noise.
• In Modelica/Media/package.mo array sizes are specified since OCT does not support this type
  of unspecified array sizes. This affects the models Modelica.Media.Examples.ReferenceAir.MoistAir,
  Modelica.Media.Examples.ReferenceAir.MoistAir1 and Modelica.Media.Examples.ReferenceAir.MoistAir2.
• In Modelica/Resources/C-Sources/ModelicaStandardTablesUsertab.c it is removed weak symbol linking for
  MacOS since MacOS doesn't support it. This affects the models using ModelicaStandardTables.
• The component m has been removed from models Modelica.Electrical.QuasiStationary.MultiPhase.Sources.FrequencySweepCurrentSource and Modelica.Electrical.QuasiStationary.MultiPhase.Sources.FrequencySweepVoltageSource to avoid non-identical duplicate components. See also the reported issue 4021 on the GitHub repository for Modelica Association (modelica#4021).

With the patches listed above applied, all example models in version 3.2.3 build 3 of MSL simulate correctly with
Modelon's OPTIMICA Compiler Toolkit (OCT).

The following changes have also been applied in order to support 3D animations in Modelon Impact:

• In file MSL323/ModelicaServices/package.mo, a number of parameters / variables have been added.
• In file MSL323/ModelicaServices/package.mo, the equation (x, y, z, C) =
  surfaceCharacteristic(nu,nv,multiColoredSurface) has been added.
• In file MSL323/ModelicaServices/package.mo, the annotation Protection(access=Access.hide) has been added.
• In directory MSL323/Modelica/Resources/Data/Shapes/Engine, the three files crank.glb, piston.glb and rod.glb
  have been added. These are files converted from their respective dxf-format in that same directory.
• In directory MSL323/Modelica/Resources/Data/Shapes/RobotR3, the six files b0.glb, b1.glb, b2.glb, b3.glb,
  b4.glb, b5.glb and b6.glb have been added. These are files converted from their respective dxf-format in that
  same directory.

Several icons in the MSL bundle of version 3.2.3 are also updated visually such that they are using a gradient fill,
this change is in line with the pull request at issue 3952 (modelica#3952).
