CONSTRUCT SET Set_Name COMPLEMENT Set_name1 [Set_name2]

           

In FEMGEN the highest order parts present in both Set_name1 and Set_name2 is determined. Any parts of this type that are in Set_name2 but not in Set_name1 are appended to the named set. The set is then completed as described in section 2.3.8. If no Set_name2 is given then the default is ALL which specifies all of the geometry.

In FEMVIEW both Set_name1 and Set_name2 must be the same type of set. The elements or nodes that are present in Set_name2 but not Set_name1 are appended to the named set. If no Set_name2 is given then the default is ALL which specifies all of the model.

Examples:

1.

CONSTRUCT SET SE5 COMPLEMENT SE1 SE2

If set SE1 contains surface S1 and set SE2 contains surfaces S1, S2, S3 and S4 then surfaces S2, S3 and S4 are appended to set SE5. Set SE5 is then completed.
