Importing Geometry to Mesh
Use a mesh Import node () to import the Component’s geometry directly to a Mesh-Based Geometry sequence or a Mesh sequence. If the geometry intersects any previously imported mesh, use a Union operation to unite them.
Figure 8-27: The geometry of two pedicle screws and a rod is imported to a mesh that already contains the imported STL mesh of two vertebrae and a disc.
Import
In the Source list, choose Geometry sequence and select a geometry sequence from the Geometry list below.
From the Face mesh generation list, select Free triangular (default) to import a triangle mesh, generated in the background by the Free Triangular operation. Specify the size of the triangles using the Size list, ranging from Extremely fine to Extremely coarse (default Normal). Select the Resolve narrow domain regions checkbox (default ON) to let the surface mesh be finer close to a thin region in the domain. Select the Resolve geometric details checkbox (default ON) to let the surface mesh be finer close to small details and curved faces. Clear the checkboxes to let the element size be determined by the Size setting only.
Select Visualization to import a visualization mesh of the geometry (3D only). Specify the level of detail for the triangulation using the Detail list, ranging from Fine to Coarse (default Normal).
To import a geometry sequence, click the Import button.
Entity Selections
The sections Domain Selections, Boundary Selections (only 3D), Edge Selections, and Point Selections appear after building the Import operation. The selections are generated during the import based on selections defined in the source. In the Name column, the name of each selection appears. For import of a geometry sequence, each name is by default the name of the selection in the original geometry that appears in the Source in geometry column. Select the name in the Name column to highlight the selection in the Graphics window. Note that not all of these selection sections are available for all space dimensions. If the Keep checkbox (ON by default) is selected, the selection is available for use in mesh operations after the Import node. If the Physics checkbox (Instance in parts) is selected (ON by default), it makes that selection also available when defining, for example, physics and materials. If you are working in a mesh part, the selection will be available in instances of the mesh part.
