Whirl
Create a whirl plot. This plot type is only available with a license for the Rotordynamics Module.
Syntax
model.result(<pgtag>).create(<ftag>,"Whirl");
model.result(<pgtag>).feature(<ftag>).set(property, <value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
 model.result(<pgtag>).create(<ftag>,"Whirl") creates a whirl plot feature named <ftag> belonging to the plot group <pgtag>.
The whirl plot creates a plot of the mode shapes of a rotor rotated about the rotor axis at discrete rotation intervals.
The following properties are available::

Property
Value
Default
Description
colortable
color table name
Rainbow
The color table to use. See Color Tables for a list of color tables.
const
String array of property/value pairs
Empty
Parameters to use in the expressions.
data
none | parent | data set name
parent
The data set this feature refers to.
descr
String
Model-dependent.
The description of the expression in expr. Is used in the automatic title.
descriptionintitle
on | off
on
Whether the title contribution should contain the description when titletype is custom.
differential
on | off
on
Whether the expression should be linearized at the linearization point. Applicable only if evalmethod is harmonic.
evalmethod
linpoint | harmonic | lintotal | lintotalavg | lintotalrms | lintotalpeak
harmonic
Applicable only for solutions with a stored linearization point. Controls if the linearization point, the perturbation, or a combination should be used when evaluating the expression.
expr
String array
Model-dependent.
The x, y, and z components of the expression to plot.
expressionintitle
on | off
off
Whether the title contribution should contain the expression when titletype is custom.
inheritcolor
Boolean
true
If inheritplot is not none: Determines if the color is inherited.
inheritplot
none | plot name
none
The plot that color and tube radius scale are inherited from.
inherittubescale
Boolean
true
If inheritplot is not none: Determines if the tube radius scale is inherited.
interp
double array
Time corresponding to last selected solnum for transient levels.
The time to use, for transient levels. Available when data is not parent and the underlying data is transient.
looplevel
array of nonnegative integers and strings
Last solution for transient or parametric solution for each level. Otherwise first solution for each level.
The index of the solution to use, per level, or interp, but only for transient solutions. Available when data is not parent and the underlying data has multiple solutions.
nplanes
nonnegative integer
4
Number of planes in the whirl plot.
nrings
nonnegative integer
4
Number of rings in the whirl plot.
outersolnum
nonnegative integer
1
The index of the outer solutions to use. Applicable only for parametric sweep models.
prefixintitle
String
Empty
Added prefix to contribution to title.
radiusexpr
String
Empty
The tube radius expression.
recover
off | pprint | ppr
off
The derivative recovery method (off, within domains, or everywhere).
refine
nonnegative integer
1
The element refinement to use, if resolution is set to manual. Bear in mind that this is the refinement used for the base data set, so the number of elements in the model can increase radically if the plot uses, for example, a revolve data set.
resolution
norefine | coarse | normal | fine | finer | extrafine | custom
normal
Controls the plot’s resolution. A finer setting results in a higher resolution by modifying the internally computed default refinement. Use custom to enter your own refinement in the refine property.
ringcolor
custom | black | blue | cyan | gray | green | magenta | red | white | yellow
blue
The color to use for the rings in the whirl plot.
smooth
none | material | internal | everywhere | expression
internal
Smoothing settings. With material, smoothing is done inside material domains With internal, smoothing is done inside geometry domains. With expression, the smoothing is based on the expression in smoothexpr.
smoothexpr
String
dom
The expression to use for smoothing when smooth is set to expression.
solnum
nonnegative integer
Last solution for transient or parametric solution. Otherwise first solution.
The index of the solution to use. Available when data is not parent and the underlying data has multiple solutions.
suffixintitle
String
Empty
Added suffix to contribution to title.
t
double
Time corresponding to last selected solnum.
The time to use, for transient problems. Available when data is not parent and the underlying data is transient.
threshold
manual | none
none
Use a smoothing threshold.
thresholdvalue
double
0.1
Threshold value (0-1), if threshold is set to manual.
timeinterp
on | off
off
on if t is used to determine time steps, off if solnum is used.
title
String
The auto-title
The title to use when titletype is manual.
titletype
auto | custom | manual | none
auto
auto if the title contribution should be computed automatically, possibly using the group’s customization. custom if the title contribution should be computed automatically, but customized. manual if the manual title contribution should be used (the title property). none if no title contribution should be used.
tuberadiusscale
double
1
The scale factor applied to the tube radii if tuberadiusscaleactive is true.
tuberadiusscaleactive
Boolean
false
If true, tuberadiusscale is used, otherwise the scale factor is computed automatically.
typeintitle
on | off
on
Whether the title contribution should contain the type when titletype is custom.
unitintitle
on | off
on
Whether the title contribution should contain the unit when titletype is custom.
