COMSOL 6.2 - DistanceMeasurement

You are viewing the documentation for an older COMSOL version. The latest version is available here.

Create parameters that measure the shortest Euclidean distance and vectorial distances between two points or between a point and an edge.

Syntax

model.component(<ctag>).geom(<tag>).create(<ftag>,"DistanceMeasurement");

model.component(<ctag>).geom(<tag>).feature(<ftag>).selection(property);

model.component(<ctag>).geom(<tag>).feature(<ftag>).set(property,<value>);

model.component(<ctag>).geom(<tag>).feature(<ftag>).getType(property);

model.component(<ctag>).geom(<tag>).feature(<ftag>).setAttribute(attribute,<value>);

model.component(<ctag>).geom(<tag>).feature(<ftag>).getAttribute(attribute);

Description

Use model.component(<ctag>).geom(<tag>).create(<ftag>,"DistanceMeasurement") to create parameters for distance and vectorial distance.

Use the following methods to specify the dimension of the second entity as well as selecting it:

model.component(<ctag>).geom(<tag>).feature(<ftag>).selection("ent2").init()

model.component(<ctag>).geom(<tag>).feature(<ftag>).selection("ent2").set()

to select the end edge, boundary or point of the measurement. The default selection is empty.

Use double[] parvalues = model.component(<ctag>).geom(<tag>).feature(<ftag>).getDoubleArray("parvalvec"); to access the parameter values (similar for parval).

Table 3-65: Valid Property/Value Pairs.
Property	Value	Default	Description
ent1	Selection		Specify a vertex as first entity.
ent2	Selection		Specify a second entity. Dimension 0 and 1 supported.
extendent	on \| off	off	Extend a straight or circular edge specified in ent2.
parname	String		Parameter names for the Euclidean distance.
parnamevec	String[]		Parameter names for the vectorial distances. The array has the length of the space dimension, sdim
parval	double		To access parameter value of Euclidean distance (read-only).
parvalvec	double[]		To access parameter values of vectorial distances (read-only).
