Accessing Mesh Data
To get the number of mesh vertices, use
int model.
component(
<ctag>
).
mesh(
<tag>
).getNumVertex();
To get the coordinates of the mesh vertices, use
double[][] model.
component(
<ctag>
).
mesh(
<tag>
).getVertex();
which gives you a matrix where each column corresponds to a mesh vertex.
To get the element types in the mesh, use
String[] model.
component(
<ctag>
).
mesh(
<tag>
).getTypes();
The following table lists the possible types. See
Mesh Element Numbering Conventions
for an explanation of each type.

To get the number of elements of a specific type, use
int model.
component(
<ctag>
).
mesh(
<tag>
).getNumElem(
type
);
To get the elements for a specific type, use
int[][] model.
component(
<ctag>
).
mesh(
<tag>
).getElem(
type
);
which gives you a matrix where each column contains the mesh vertex indices of an element’s corners.
To get the geometric entity number for the elements of a specific type, use
int[] model.component(
<ctag>
).mesh(
<tag>
).getElemEntity(
type
);
To return the tags of imported mesh selections, use
String[] outputSelection();
The tag for the corresponding selection feature can then be derived by adding component tag and feature tag in front of the mesh selection tag. For example, if a mesh selection feature is imported by a feature
imp1
in component
comp1
, and its tag (returned by the function
outputSelection()
) is
mytag
, the tag of the selection feature is
comp1_imp1_mytag
.
