Hi,
select the area, then issue
NSLA,<selection method>,<selection option>
where:
- <selection method> is s (select from full set), r (reselect from curent selection), a (add to current selection), or u (unselect from current selection) as usual
- <selection option> is 1 (all nodes on surface, including shared boundaries) or 0 (only interior nodes of surface).
Regards
