Description

Version 3.2 is backward compatible to version 3.1, i.e., models developed withversions 3.0, 3.0.1, or 3.1 will work without any changes also with version 3.2.This version is a major improvement:

  • 357 models and blocks and 295 functions are newly included.
  • 7 new libraries are included.
  • The icons of the library are newly designed to provide a modern, unified view, see Modelica.Icons.
  • All non-Modelica files, such as images, pdf-files, C-source files, scripts are moved to the new directory "Modelica\\Resources". Furthermore, all file references are changed to URIs as introduced in Modelica 3.1 (e.g., a file with the file name "Modelica/Resources/Images/xxx" is referenced as "../../../Resources/Images/xxx").
  • All physical models that dissipate heat (such as electrical elements, electrical machines, bearings, dampers, etc.), have now an optional heat port to which the dissipated energy is flowing, if activated. This will significantly improve design studies about the thermal efficiency of technical systems.
  • All electrical machines in the Machines library have now a "Losses" tab in the parameter menu to optionally model machines losses such as frictional losses, stator core losses or stray load losses, respectively.
  • All electrical machines in the Machines library have now a "powerBalance" result record, summarizing converted power and losses.

Version 3.2 is slightly based on the Modelica Specification 3.2. It usesthe following new language elements (compared to Modelica Specification 3.1):

  • Operator records and overloaded operators.
  • Functions as input arguments to functions.
  • Improved expandable connectors (variables declared in expandable connectors are ignored if not referenced).

A large part of the new classes have been developed withpartial financial support byBMBF(BMBF Förderkennzeichen: 01IS07022F)within the ITEA2 projectEUROSYSLIB.We highly appreciate this funding.

The following new libraries have been added:

Complex This is a top-level record outside of the Modelica Standard Library. It is used for complex numbers and contains overloaded operators. From a users point of view, Complex is used in a similar way as the built-in type Real. Example:
  Real a = 2;
  Complex j = Modelica.ComplexMath.j;
  Complex b = 2 + 3*j;
  Complex c = (2*b + a)/b;
  Complex d = Modelica.ComplexMath.sin(c);
  Complex v[3] = {b/2, c, 2*d};
(This library was developed by Marcus Baur, DLR).
Modelica.ComplexBlocks Library of basic input/output control blocks with Complex signals.
This library is especially useful in combination with the new Modelica.Electrical.QuasiStationary library in order to build up very fast simulations of electrical circuits with periodic currents and voltages.
(This library was developed by Anton Haumer).
Modelica.Electrical.QuasiStationary Library for quasi-stationary electrical singlephase and multiphase AC simulation.
This library allows very fast simulations of electrical circuits with sinusoidal currents and voltages by only taking into account the quasi-stationary, periodic part and neglecting non-periodic transients.
(This library was developed by Anton Haumer and Christian Kral).
Modelica.Electrical.Spice3 Library with components of the Berkeley SPICE3 simulator:
R, C, L, controlled and independent sources, semiconductor device models (MOSFET Level 1, Bipolar junction transistor, Diode, Semiconductor resistor). The components have been intensively tested with more than 1000 test models and compared with results from the SPICE3 simulator. All test models give identical results in Dymola 7.4 with respect to the Berkeley SPICE3 simulator up to the relative tolerance of the integrators.
This library allows detailed simulations of electronic circuits. Work on Level 2 SPICE3 models, i.e., even more detailed models, is under way. Furthermore, a pre-processor is under development to transform automatically a SPICE netlist into a Modelica model, in order that the many available SPICE3 models can be directly used in a Modelica model.
(This library was developed by Fraunhofer Gesellschaft, Dresden).
Modelica.Magnetic.FundamentalWave Library for magnetic fundamental wave effects in electric machines for the application in three phase electric machines. The library is an alternative approach to the Modelica.Electrical.Machines library. A great advantage of this library is the strict object orientation of the electrical and magnetic components that the electric machines models are composed of. This allows an easier incorporation of more detailed physical effects of electrical machines. From a didactic point of view this library is very beneficial for students in the field of electrical engineering.
(This library was developed by Christian Kral and Anton Haumer, using ideas and source code of a library from Michael Beuschel from 2000).
Modelica.Fluid.Dissipation Library with functions to compute convective heat transfer and pressure loss characteristics.
(This library was developed by Thorben Vahlenkamp and Stefan Wischhusen from XRG Simulation GmbH).
Modelica.ComplexMath Library of complex mathematical functions (e.g., sin, cos) and of functions operating on complex vectors.
(This library was developed by Marcus Baur from DLR-RM, Anton Haumer, and HansJürg Wiesmann).

The following existing componentshave been improved in abackward compatible way:

Modelica.Blocks.Sources.
Pulse
SawTooth 		New parameter "nperiod" introduced to define the number of periods for the signal type. Default is "infinite number of periods (nperiods=-1).
Modelica.Electrical.
MultiPhase.* All dissipative components have now an optional heatPort connector to which the dissipated losses are transported in form of heat.
Machines.* To all electric machines (asynchronous and synchronous induction machines, DC machines) and transformers loss models have been added (where applicable):
Temperature dependent resistances (ohmic losses)
Friction losses
Brush losses
Stray Load losses
Core losses (only eddy current losses but no hysteresis losses; not for transformers)
As default, temperature dependency and losses are set to zero.

To all electric machines (asynchronous and synchronous induction machines, DC machines) and transformers conditional thermal ports have been added, to which the dissipated losses are flowing, if activated. The thermal port contains a HeatPort for each loss source of the specific machine type.

To all electric machines (asynchronous and synchronous induction machines, DC machines) a "powerBalance" result record has been added, summarizing converted power and losses.
Modelica.Mechanics.
MultiBody.*
Rotational.*
Translational.*		 All dissipative components in Modelica.Mechanics have now an optional heatPort connector to which the dissipated energy is transported in form of heat.
All icons in Modelica.Mechanics are unified according to the Modelica.Blocks library:
"%name": width: -150 .. 150, height: 40, color: blue
other text: height: 30, color: black
Modelica.Mechanics.MultiBody.
World Function gravityAcceleration is made replaceable, so that redeclaration yields user-defined gravity fields.
Modelica.Fluid.Valves.
ValveIncompressible
ValveVaporizing
ValveCompressible		 (a) Optional filtering of opening signal introduced to model the delay time of the opening/closing drive. In this case, an optional leakageOpening can be defined to model leakage flow and/or to improve the numerics in certain situations. (b) Improved regularization of the valve characteristics in some cases so that it is twice differentiable (smooth=2), instead of continuous (smooth=0).
Modelica.Fluid.Sources.
FixedBoundary
Boundary_pT
Boundary_ph		 Changed the implementation so that no non-linear algebraic equation system occurs, if the given variables (e.g. p,T,X) do not correspond to the medium states (e.g. p,h,X). This is achieved by using appropriate "setState_xxx" calls to compute the medium state from the given variables. If a nonlinear equation system occurs, it is solved by a specialized handler inside the setState_xxx(..) function, but in the model this equation system is not visible.
Modelica.Media.Interfaces.
PartialMedium The min/max values of types SpecificEnthalpy, SpecificEntropy, SpecificHeatCapacity increased, due to reported user problems.
New constant C_nominal introduced to provide nominal values for trace substances (utilized in Modelica.Fluid to avoid numerical problems; this fixes ticket #393).
Modelica.Thermal.
HeatTransfer.* All icons are unified according to the Modelica.Blocks library:
"%name": width: -150 .. 150, height: 40, color: blue
other text: height: 30, color: black
Modelica.Math.Matrices
QR A Boolean input "pivoting" has been added (now QR(A, pivoting)) to provide QR-decomposition without pivoting (QR(A, false)). Default is pivoting=true.


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

Modelica.Electrical.Digital.Delay.
InertialDelaySensitive In order to decide whether the rising delay (tLH) or the falling delay (tHL) is used, the "previous" value of the output y has to be used and not the "previous" value of the input x (delayType = delayTable[y_old, x] and not delayType = delayTable[x_old, x]). This has been corrected.
Modelica.Mechanics.MultiBody.Parts.
BodyBox
BodyCylinder 		Fixes ticket #373: The "Center of Mass" was calculated as normalize(r)*length/2. This is only correct if the box/cylinder is attached between frame_a and frame_b. If this is not the case, the calculation is wrong. The has been fixed by using the correct formula:
r_shape + normalize(lengthDirection)*length/2
BodyShape
BodyBox
BodyCylinder 		Fixes ticket #300: If parameter enforceStates=true, an error occurred. This has been fixed.
Modelica.Mechanics.Rotational.Components.
LossyGear In cases where the driving flange is not obvious, the component could lead to a non-convergent event iteration. This has been fixed (a detailed description is provided in ticket #108 and in the attachment of this ticket).
Gearbox If useSupport=false, the support flange of the internal LossyGear model was connected to the (disabled) support connector. As a result, the LossyGear was "free floating". This has been corrected.
Modelica.Fluid.Pipes.
DynamicPipe Bug fix for dynamic mass, energy and momentum balances for pipes with nParallel>1.
Modelica.Fluid.Pipes.BaseClasses.HeatTransfer.
PartialPipeFlowHeatTransfer Calculation of Reynolds numbers for the heat transfer through walls corrected, if nParallel>1. This partial model is used by LocalPipeFlowHeatTransfer for laminar and turbulent forced convection in pipes.
Modelica.Media.Interfaces.PartialLinearFluid
setState_psX Sign error fixed.
Modelica.Media.CompressibleLiquids.
LinearColdWater Fixed wrong values for thermal conductivity and viscosity.


The following uncritical errors have been fixed (i.e., errorsthat do not lead to wrong simulation results, but, e.g.,units are wrong or errors in documentation):

Modelica.Math.Matrices.LAPACK
dgesv_vec
dgesv
dgetrs
dgetrf
dgetrs_vec
dgetri
dgeqpf
dorgqr
dgesvx
dtrsyl		 Integer inputs to specify leading dimensions of matrices have got a lower bound 1 (e.g., lda=max(1,n)) to avoid incorrect values (e.g., lda=0) in the case of empty matrices.
The Integer variable "info" to indicate the successful call of a LAPACK routine has been converted to an output where it had been a protected variable.
