Box
Use a Box node () to split geometric entities of an imported mesh by creating at least one new geometric entity for the elements enclosed in the specified box.
To add a Box node, right-click a 2D or 3D mesh node and select Box from the Partitions menu. Then use the following sections to specify the geometric entities to split, the properties of the box, and the split condition:
Geometric Entity Selection
Define the geometric entities that you want to split. You choose the geometric entity level from the Geometric entity level list:
•
Choose Entire geometry to split 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 split. 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 enclosed, or choose Some vertex to consider it enclosed if at least one element vertex is enclosed.
