CONSTRUCT SET Set_name INTERSECT Set_name1 Set_name2

           

In FEMGEN the highest order part present in both Set_name1 and Set_name2 is determined. Any parts of this type that are in both sets are appended to the named set. The set is then completed as described in section 2.3.8.

In FEMVIEW both Set_name1 and Set_name2 must be the same type of set. The elements or nodes that are present in both Set_name1 and Set_name2 are appended to the named set.

Examples:

1.

CONSTRUCT SET SE5 INTERSECT SET3 SET4

Assuming SET3 contains body B1 with surfaces S1, S2, S3, S4 and S5 and SET4 contains body B2 with surfaces S5, S6, S7, S8 and S9. Surface S5 will be appended to SE5. This set will then be completed by the addition of all the parts that make up S5.

2.

CONSTRUCT SET SE3 INTERSECT SE1 SE2

If SE1 contains surface S1 and SE2 contains all of the geometry then S1 is appended to SE3 and it is then completed.
