Partition with Box
Use a Partition with Box node () to partition geometric entities of an imported mesh by creating at least one new geometric entity for the elements enclosed in the specified box.
Figure 8-52: Using a Partition with Box node to define the mounting holes on the feeder clamp.
To add a Partition with Box node, right-click a 2D or 3D Mesh or Mesh Part node and select Partition with Box from the Intersection and Partitions menu. That menu is also available on the Mesh toolbar.
Note that partitioning a mesh can modify the number of geometric entities. Thus when you are adding this operation to a meshing sequence that is conforming with the component's geometry, a new meshing sequence that is defining its own geometric model is automatically created, and the Partition with Box node is added to this new sequence. For more information see The Mesh Node.
Then use the following sections to specify the geometric entities to partition, the properties of the box, and the condition for division:
Geometric Entity Selection
Define the geometric entities that you want to partition. You choose the geometric entity level from the Geometric entity level list:
•
Choose Entire geometry to divide all geometric entities according to the specified box.
•
Choose Domain, Boundary, or Edge to specify the domains, boundaries, or edges, respectively, that you want to partition. Use All domains, All boundaries, or All edges to select all entities of the specified dimension.
Box Limits
Specify the limits of the box in the x minimum, x maximum, y minimum, y maximum, z minimum (3D only), and z maximum (3D only) fields.

Condition
Use the Include element if box contains list to select the condition for which an element is enclosed in the specified box. Choose All vertices to consider an element to be enclosed in the specified box if all element vertices are inside, or choose Some vertex to consider it enclosed if at least one element vertex is inside the box.
