You can add mesh parts from the Global Definitions node (
) by right-clicking it and, from the
Mesh Parts submenu, select
3D Part,
2D Part, or
1D Part. If a
Mesh Parts node (
) already exists under
Global Definitions, you can add another mesh part by right-clicking it and then select
3D Part,
2D Part, or
1D Part.
Under a Mesh Part node you add nodes for importing and modifying an externally generated mesh. An
Import node (see
Importing Meshes) is automatically added to import a mesh. In 2D and 3D, you can then add additional nodes for partitioning the mesh, deleting and joining entities, creating entities, and
Remeshing Imported Meshes. Such operations can be useful to define additional domains, for example. There is also a
View node with view settings (see
User-Defined Views) below the mesh feature nodes.
In a geometry sequence or part you can create an instance of the mesh part by right-clicking the Geometry node and adding an
Import node (see
Import in the
Geometry Modeling and CAD Tools chapter). Then choose
Mesh or STL (in 3D) or
Mesh (in 1D and 2D) from the
Source list and choose the mesh part from
Mesh list below to use the mesh part in the geometry sequence.
The Settings window for a
Mesh Part node contains the following sections:
Select the Build new operations automatically check box to allow new operations for this mesh part to build automatically. Clear the check box to require that the
Build Selected or
Build All buttons are clicked in order for the operations to build. The default value is controlled by the preference setting
Mesh>Build new operations automatically. Select
In new meshes check box to always build operations directly, unless overridden by the settings for an individual mesh part.
For mesh files that are unitless, the physical size of an imported mesh is independent of the length unit of the mesh part. For mesh files that define a unit, the imported mesh is scaled to match the unit of the mesh part, if the Use units check box is selected. You can also select this check box to use the length unit and angular unit (which you specify using the
Length unit list and
Angular unit list, respectively) in the nodes appearing under the
Mesh Part node and to specify the length unit of the resulting file when exporting the mesh to a file format that supports length units.
