Package-specific Changes

• All example models made encapsulated
• Upper case constants changed to lower case (cf. Modelica.Constants)
• Introduced Modelica.SIunits.Wavelength due to typo "Wavelenght"
• Introduced ModelicaAdditions.Blocks.Logical.Interfaces.Comparison due to typo "Comparision"
• Changed these components of *.Blocks to block class, which have not been already of block type
• Changed *.Interfaces.RelativeSensor to partial models

Class-specific Changes

Modelica.SIunits

Removed final from quantity attribute for Mass and MassFlowRate.

Modelica.Blocks.Math.Sum

Implemented avoiding algorithm section, which would lead to expensive function calls.

Modelica.Blocks.Sources.Step

block Step "Generate step signals of type Real"
        parameter Real height[:]={1} "Heights of steps";
 // parameter Real offset[:]={0} "Offsets of output signals";
// parameter SIunits.Time startTime[:]={0} "Output = offset for time < startTime";
// extends Interfaces.MO          (final nout=max([size(height, 1); size(offset, 1); size(startTime, 1)]));
        extends Interfaces.SignalSource(final nout=max([size(height, 1); size(offset, 1); size(startTime, 1)]));

Modelica.Blocks.Sources.Exponentials

Replaced usage of built-in function exp by Modelica.Math.exp.

Modelica.Blocks.Sources.TimeTable

Interface definition changed from

    parameter Real table[:, :]=[0, 0; 1, 1; 2, 4] "Table matrix (time = first column)";

to

    parameter Real table[:, 2]=[0, 0; 1, 1; 2, 4] "Table matrix (time = first column)";

Did the same for subfunction getInterpolationCoefficients.

Bug in getInterpolationCoefficients for startTime <> 0 fixed:

        ...
                end if;
          end if;
          // Take into account startTime "a*(time - startTime) + b"
          b := b - a*startTime;
        end getInterpolationCoefficients;

Modelica.Blocks.Sources.BooleanStep

block BooleanStep "Generate step signals of type Boolean"
        parameter SIunits.Time startTime[:]={0} "Time instants of steps";
        parameter Boolean startValue[size(startTime, 1)]=fill(false, size(startTime, 1)) "Output before startTime";
        extends Interfaces.BooleanSignalSource(final nout=size(startTime, 1));
equation
        for i in 1:nout loop
//   outPort.signal[i] = time >= startTime[i];
          outPort.signal[i] = if time >= startTime[i] then not startValue[i] else startValue[i];
        end for;
end BooleanStep;

Modelica.Electrical.Analog

Corrected table of values and default for Beta by dividing them by 1000 (consistent with the values used in the NAND-example model):

• Semiconductors.PMOS
• Semiconductors.NMOS

Corrected parameter defaults, unit and description for TrapezoidCurrent. This makes the parameters consistent with their use in the model. Models specifying parameter values are not changed. Models not specifying parameter values did not generate trapezoids previously.

Icon layer background changed from transparent to white:

• Basic.Gyrator
• Basic.EMF
• Ideal.Idle
• Ideal.Short

Basic.Transformer: Replaced invalid escape characters '\\ ' and '\\[newline]' in documentation by '|'.

Modelica.Mechanics.Rotational

Removed arrows and names documentation from flanges in diagram layer

Modelica.Mechanics.Rotational.Interfaces.FrictionBase

Modelica.Mechanics.Rotational.Position

Replaced reinit by initial equation

Modelica.Mechanics.Rotational.RelativeStates

Bug corrected by using modifier stateSelect = StateSelect.prefer as implementation

Modelica.Mechanics.Translational.Interfaces.flange_b

Attribute fillColor=7 added to Rectangle on Icon layer, i.e., it is now filled with white and not transparent any more.

Modelica.Mechanics.Translational.Position

Replaced reinit by initial equation

Modelica.Mechanics.Translational.RelativeStates

Bug corrected by using modifier stateSelect = StateSelect.prefer as implementation

Modelica.Mechanics.Translational.Stop

Use stateSelect = StateSelect.prefer.

Modelica.Mechanics.Translational.Examples.PreLoad

Improved documentation and coordinate system used for example.

ModelicaAdditions.Blocks.Nonlinear.PadeDelay

Replaced reinit by initial equation

ModelicaAdditions.HeatFlow1D.Interfaces

Definition of connectors Surface_a and Surface_b:
flow SIunits.HeatFlux q; changed to flow SIunits.HeatFlowRate q;

MultiBody.Parts.InertialSystem

Icon corrected.
