Boolean operations ANSYS APDL

1. intersection operation

The results from the intersection operation is common portion of each of the initial elements, forming a new element.

command	Features	Remark
LINL	And cross-wire line
ALWAYS	Deposit surface and the surface
VINV	And cross-member body
LINA	And plane intersection line
AINV	The surface of the cross member
LINP	Twenty-two line of intersection
Ainf	Twenty-two intersecting surfaces
VINP	Twenty-two intersection body

2. add operation

Add operation result of the original elements comprising all portions of the new entity. This operation is also known as and, or and connected. The new entity is thus formed a single whole, no seam. In reality, elements formed not as overlap add operation is formed in the mesh primitive good . Only the two-dimensional plane and three-dimensional solid is coplanar add operation

command	Features	Remark
aADD	Plus face
WADDING	Adding body

3. subtraction

If a primitive is subtracted from (E1) to another entity (E2 of), the structure of which there are two cases, one to generate one or more new primitives (E3), E3 and E1 have the same dimension and with no E2 overlapping portion; another case E1 and E2 overlapping portion is a low-dimensional entity, the result is two or more new entity E1 is divided.

command	Features	Remark
LSBL	Subtracted from the line line
ASBA	Subtracted from the surface plane
VSBV	From the body minus the body
LSBA	Subtracting from the thread surface
LSBV	Subtracting from the body line
ASBV	Subtracting from the body surface
ASBL	Subtracting from a face line	？？？
VSBA	Subtracting from the body surface	？？？

4. division

Work plane can be used for segmentation operation, a primitive is divided into two or more elements.

command	Features	Remark
LSBW	Working parting line plane
ASBW	Work plane division surface
VSBW	Working plane divided body

5. Lap

FIG lap element for connecting two or more elements to generate a set of three or more primitive. In addition to the overlapping operation field generated around the plurality of overlapping outer boundary, and add operations are very similar. Overlap region must have the same number of dimensions as the original element. A common connection plane.

command	Features	Remark
LOVLAP	Bonding wire
AOVLAP	Lap face
VOVLAP	Lap body

6. Mutual min

For mutually connecting two or more sub-elements to generate a set of three or more new primitives. If the overlapping area of ​​the original elements have the same dimensions, the mutual partial overlap with the same results as the results. But the overlap is different, did not join the lap of the input entities will not be deleted.

command	Features	Remark
LPTN	Mutual division line
APTN	Surface cross points
VPTN	Partial cross member

6. bond

粘结命令与搭接命令类似，只是图元之间仅在公共边界处相关，且公共边界的维数低于原始图元一维。这些图元之间仍然相互独立，只在边界上的连接。

命令	功能	备注
LGLUE	线粘接
AGLUE	面粘接
VGLUE	体粘接
