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:

About 557 issues (including pull requests) have been addressed for this release.
94 component models and blocks, 36 example models and 9 functions are newly included.
The license has been changed to BSD 3-clause, visit: https://modelica.org/licenses/modelica-3-clause-bsd.

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

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
TimeTable	The derivative of the `TimeTable` output could no longer be determined. This has been corrected.
Modelica.Media.Air
MoistAir.molarMass ReferenceMoistAir.molarMass	The computation of the function output `MM` was wrong. This has been corrected.
Modelica.Media.IdealGases.Common.Functions
thermalConductivityEstimate	The computation of the function output `lambda` was wrong for the modified Eucken correlation, i.e., if `method` is set to 2. This has been corrected.
Modelica.Media.IdealGases.Common.SingleGasesData
CH2 CH3 CH3OOH C2CL2 C2CL4 C2CL6 C2HCL C2HCL3 CH2CO_ketene O_CH_2O HO_CO_2OH CH2BrminusCOOH C2H3CL CH2CLminusCOOH HO2 HO2minus OD ODminus	The coefficients for `blow`, `ahigh` and `bhigh` were wrong. This has been corrected.
Modelica.Media.IdealGases.Common.MixtureGasNasa
mixtureViscosityChung	The computation of the function output `etaMixture` was wrong. This has been corrected.
Modelica.Media.Incompressible.TableBased
BaseProperties	The unit of the gas constant `R` for table based media was not correctly considered. This has been corrected.
Modelica.Math.Random.Utilities
impureRandomInteger	The function output `y` was not computed to yield a discrete uniform distribution for a minimum value `imin` of 1. This has been corrected.
