Note:

Any number of nodes can be inserted in one line. Any number of lines can be inserted until the next option starts.

It is necessary to define the nodes to be specified before "!NGROUP".

The node not defined in the "!NODE" option will be excluded, and a warning message will be displayed.

When the specified node exists in the same group, it will be ignored and a warning message will be displayed.

All the nodes belong to the node group named "ALL" (generated automatically).

One group can be defined by dividing into multiple groups.

Example of Use

!NGROUP, NGRP=NA01
1, 2, 3, 4, 5, 6
101, 102
!NGROUP, NGRP=NA02
101, 102
!NGROUP, NGRP=NA01                   ----- "501 and 505" are added to group "NA01".
501, 505
!NGROUP, NGRP=NA02                   ----- "501 and 505" are added to group "NA02".
501, 505
!NGROUP, NGRP=NA04,GENERATE          ----- "301, 303, 305, 307, 309, 311, 312, 313"
