COMSOL 6.2 - Deform

model.result(<pgtag>).feature(<ftag>).create(<atag>,"Deform");

model.result(<pgtag>).feature(<ftag>).feature(<atag>).set(property,<value>);

model.result(<pgtag>).feature(<ftag>).create(<atag>,"Deform") creates a deformation attribute feature with the name <atag>, belonging to the feature <ftag>.

Deformation attributes deform the coordinates of a plot feature according to an expression (typically, the displacement in a structural mechanics model). The deformation attribute can be added to arrow plots; contour plots; isosurface plots; particle plots; pellets plots; slice plots; streamline, streamline multislice, and streamline surface plots; surface plots; volume plots; and mesh plots.

The following properties are available:

Table 7-28: Valid Property/Value Pairs for Deform.
Property	Value	Default	Description
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	Model dependent	The expression to plot.
maxreldeformexpr	String	"0,1"	Maximum relative deformation as a fraction of the mean size of the geometry’s bounding box.
prefixintitle	String	Empty	Added prefix to contribution to title.
revcoordsys	cylindrical \| cartesian	cartesian	Coordinate system for the deformation vector. Available for plots that use a Revolution 1D or Revolution 2D dataset that has default axis settings and points to a solution or mesh dataset for an axisymmetric geometry and for plots using a Mirror dataset applied to a Revolution 2D dataset.
scale	positive double	Model dependent	The scale factor for the deformation.
scaleactive	on \| off	off	Whether to use the automatically computed scale, or the scale in the scale property.
suffixintitle	String	Empty	Added suffix to contribution to title.
title	String	The auto-title	The title to use when titletype is manual.
titletype	auto \| custom \| label \| manual \| none	auto	auto, if the title should be computed automatically. custom, if the title should be computed automatically, but customized. label, if the title should be the plot group’s label. manual, if the manual title should be used (the title property). none, if no title should be displayed.
typeintitle	on \| off	on	Whether the title contribution should contain the type when titletype is custom.
unit	String	Model dependent	The unit to use for the expression in expr. If the old unit is not valid when the expression changes, the unit property is reset to default.
