Version 3.2.2 is backward compatible to version 3.2.1, that is models developed with versions 3.0, 3.0.1, 3.1, 3.2, or 3.2.1 will work without any changes also with version 3.2.2 (with exception of the, usually uncritical, non-backwards compatible changes listed below with regards to external object libraries, and one bug fix introduced in 3.2.1 Build.3 for non-circular pipes that can be non-backwards compatible if a user constructed a new pipe model based on Modelica.Fluid.Pipes.BaseClasses.WallFriction.PartialWallFriction, see details below).

The exact difference between package Modelica version 3.2.2 and version 3.2.1 is summarized in the following two comparison tables:

This release of package Modelica, and the accompanying ModelicaTest, has been tested with the following tools (the tools are listed alphabetically. At the time of the test, some of the tools might not yet supported the complete Modelica package. For more details of the tests see #1867):

The following Modelica packages have been tested that they work together with this release of package Modelica (alphabetical list):

The following new libraries have been added:

Modelica.Electrical.PowerConverters This library offers models for rectifiers, inverters and DC/DC-converters.
(This library was developed by Christian Kral and Anton Haumer).
Modelica.Magnetic.QuasiStatic.FundamentalWave This library provides quasi-static models of multiphase machines (induction machines, synchronous machines) in parallel (with the same parameters but different electric connectors) to the transient models in Modelica.Magnetic.FundamentalWave.
Quasistatic means that electric transients are neglected, voltages and currents are supposed to be sinusoidal. Mechanical and thermal transients are taken into account.
This library is especially useful in combination with the Modelica.Electrical.QuasiStationary library in order to build up very fast simulations of electrical circuits with sinusoidal currents and voltages.
(This library was developed by Christian Kral and Anton Haumer).
Sublibraries of Modelica.Magnetic.FluxTubes New elements for modeling ferromagnetic (static) and eddy current (dynamic) hysteresis effects and permanent magnets have been added. The FluxTubes.Material package is also extended to provide hysteresis data for several magnetic materials. These data is partly based on own measurements. For modeling of ferromagnetic hysteresis, two different hysteresis models have been implemented: The simple Tellinen model and the considerably more detailed Preisach hysteresis model. The following packages have been added: (These extensions have been developed by Johannes Ziske and Thomas Bödrich as part of the Clean Sky JTI project; project number: 296369; Theme: JTI-CS-2011-1-SGO-02-026; MOMOLIB - Modelica Model Library Development for Media, Magnetic Systems and Wavelets. The partial financial support by the European Union for this development is highly appreciated.).
Sublibraries for noise modeling Several new sublibraries have been added allowing the modeling of reproducible noise. The most important new sublibraries are (for more details see below): (These extensions have been developed by Andreas Klöckner, Frans van der Linden, Dirk Zimmer, and Martin Otter from DLR Institute of System Dynamics and Control).
Modelica.Utilities functions for matrix read/write New functions are provided in the Modelica.Utilities.Streams sublibrary to write matrices in MATLAB MAT format on file and read matrices in this format from file. The MATLAB MAT formats v4, v6, v7 and v7.3 (in case the tool supports HDF5) are supported by these functions. Additionally, example models are provided under Modelica.Utilities.Examples to demonstrate the usage of these functions in models. For more details see below.
(These extensions have been developed by Thomas Beutlich from ITI GmbH).
Modelica.Math sublibrary for FFT The new sublibrary FastFourierTransform provides utility and convenience functions to compute the Fast Fourier Transform (FFT). Additionally two examples are present to demonstrate how to compute an FFT during continuous-time simulation and store the result on file. For more details see below.
(These extensions have been developed by Martin Kuhn and Martin Otter from DLR Institute of System Dynamics and Control).

The following new components have been added to existing libraries:

NoiseExamples Several examples to demonstrate the usage of the blocks in the new sublibrary Blocks.Noise.
PartialNoise Partial noise generator (base class of the noise generators in Blocks.Noise)
ContinuousMean Calculates the empirical expectation (mean) value of its input signal
Variance Calculates the empirical variance of its input signal
StandardDeviation Calculates the empirical standard deviation of its input signal
GlobalSeed Defines global settings for the blocks of sublibrary Noise, especially a global seed value is defined
UniformNoise Noise generator with uniform distribution
NormalNoise Noise generator with normal distribution
TruncatedNormalNoise Noise generator with truncated normal distribution
BandLimitedWhiteNoise Noise generator to produce band-limited white noise with normal distribution
ShowTransferFunction Example to demonstrate the usage of the block TransferFunction.
TransferFunction This block allows to define a complex transfer function (depending on frequency input w) to obtain the complex output y.
LogFrequencySweep The logarithm of w performs a linear ramp from log10(wMin) to log10(wMax), the output is the decimal power of this logarithmic ramp.
ControlledDCDrives Current, speed and position controlled DC PM drive
SpringDamperNoRelativeStates Introduced to fix ticket 1375
ElastoBacklash2 Alternative model of backlash. The difference to the existing ElastoBacklash component is that an event is generated when contact occurs and that the contact torque changes discontinuously in this case. For some user models, this variant of a backlash model leads to significantly faster simulations.

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

HeatingDiode Removed protected variable k "Boltzmann's constant".
Calculate protected constant q "Electron charge" from already known constants instead of defining a protected variable q.
Removed parameter K "Boltzmann's constant" and q "Elementary electronic charge".
Calculate instead protected constant q "Electron charge" from already known constants.
Users that have used these parameters might have broken their models; the (although formal non-backwards compatible) change offers the users a safer use.
