COMSOL 6.3 - Cylinder

Split geometric entities of an imported mesh by a cylinder.

model.component(<ctag>).mesh(<tag>).create(<ftag>,"Cylinder");

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

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

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

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"Cylinder") to split geometric entities of an imported 3D mesh by an element set defined by a cylinder.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection() to specify geometric entities to split. If you do not specify the selection, the feature operates on the entire geometry.

The following properties are available:

Table 4-39: Available Properties.
Property	Value	Default	Description
r	double	1	Radius of the cylinder.
top	double	inf	Coordinate of upper boundary circle in local coordinate system.
bottom	double	-inf	Coordinate of lower boundary circle in local coordinate system.
pos	double[]	{0,0,0}	Position of the cylinder.
axistype	x \| y \| z \| Cartesian \| spherical	z	Coordinate system used for axis. The value is synchronized with axis.
axis	double[]	{0,0,1}	Direction of the axis. Vector has length 3 if axistype is cartesian, and length 2 if axistype is spherical.
condition	allvertices \| somevertex	allvertices	Condition for inclusion of an element.
selinside	on \| off	off	Create selection of all entities inside the cylinder.
seloutside	on \| off	off	Create selection of all entities outside the cylinder.

Table 4-40: Available Additional Properties When selinside and seloutside are SET to on.
Property	Value	Default	Description
colorinside	none \| custom \| integer between 1 and the number of colors in the current theme	none	The color of the domain selection, either given as an integer indicating a color in the color theme, or as a custom color in the customcolorinside property.
coloroutside	none \| custom \| integer between 1 and the number of colors in the current theme	none	The color of the domain selection, either given as an integer indicating a color in the color theme, or as a custom color in the customcoloroutside property.
customcolorinside	RGB-triplet	Next available theme color	The color to use. Active when colorinside is set to custom.
customcoloroutside	RGB-triplet	Next available theme color	The color to use. Active when coloroutside is set to custom.
selinsideshow	all \| dom \| bnd \| pnt \| off	dom	Show the selection on the specified entity level in physics, materials, and so on. For mesh parts, this option shows selection outside the part.
seloutsideshow	all \| dom \| bnd \| pnt \| off	dom	Show the selection on the specified entity level in physics, materials, and so on. For mesh parts, this option shows selection outside the part.
