Version_3_2_3

Version 3.2.3 (January 23, 2019)

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Version 3.2.3 is backward compatible to version 3.2.2, that is models developed with versions 3.0, 3.0.1, 3.1, 3.2, 3.2.1 or 3.2.2 will work without any changes also with version 3.2.3. This version is a "clean-up" with major emphasis on quality improvement and tool compatibility. The goal is that all Modelica tools will support this package and will interpret it in the same way. Short Overview:

The exact difference between package Modelica version 3.2.3 and version 3.2.2 is summarized in a comparison table.


The following new libraries have been added:

Modelica.Magnetic.QuasiStatic.FluxTubes This library provides models for the investigation of quasi-static electromagnetic devices with lumped magnetic networks in a comparable way as Modelica.Magnetic.FluxTubes.
(This library was developed by Christian Kral.)
Modelica.Electrical.Machines.Examples.ControlledDCDrives This library demonstrates the control of a permanent magnet dc machine: current control, speed control and position control along with the necessary components in sublibrary Utilities.
(This library was developed by Anton Haumer.)

The following existing components have been improved in a backward compatible way:

Modelica.Blocks.Continuous
Integrator
LimIntegrator
Added optional reset and set value inputs.
LimPID Added an optional feed-forward input.
Modelica.Blocks.Sources
CombiTimeTable The time events were not considered at the interval boundaries in case of linear interpolation and non-replicated sample points. This has been generalized by introduction of the new parameter timeEvents with the default option to always generate time events at the interval boundaries, which might lead to slower, but more accurate simulations.
BooleanTable
IntegerTable
Added options to set start time, shift time and extrapolation kind, especially to set periodic extrapolation.
Modelica.Blocks.Tables
CombiTable1D
CombiTable1Ds
CombiTable2D
Added option to set the extrapolation kind and to optionally print a warning in case of extrapolated table input.


The following existing components have been changed in a non-backward compatible way:

Modelica.Blocks
Interfaces.PartialNoise
Noise.UniformNoise
Noise.NormalNoise
Noise.TruncatedNormalNoise
Noise.BandLimitedWhiteNoise
As a side-effect of the corrected computation in Modelica.Math.Random.Utilities.impureRandomInteger the localSeed parameter is computed differently if useAutomaticLocalSeed is set to true.
Modelica.Mechanics.MultiBody
World Added new parameter animateGround for optional ground plane visualization.
Users that have copied the World model (of MSL 3.0, 3.0.1, 3.1, 3.2, 3.2.1, or 3.2.2) as an own World model and used it as inner world component, might have broken their models. Generally, for MSL models with sub-typing (due to inner/outer), it is strongly suggested to extend from this MSL model, instead of copying it.
Modelica.Media.Interfaces
PartialMedium Added new constant C_default as default value for the trace substances of medium.
Users that have created an own medium by inheritance from the PartialMedium package and already added the C_default constant, might have broken their models.
Users that have copied the PartialMedium package (of MSL 3.0, 3.0.1, 3.1, 3.2, 3.2.1, or 3.2.2) as an own Medium package, might have broken their models. Generally, for MSL classes with sub-typing (due to a replaceable declaration), it is strongly suggested to extend from this MSL class, instead of copying it.


The following critical errors have been fixed (i.e., errors that can lead to wrong simulation results):

Modelica.Blocks.Sources
