How to select all circumferential nodes in a meshed hole by selecting any one node among them?

Please tell me the tcl command

Try to select 'by face':

No, selection of node by face will select all nodes. I need just 3 other nodes after selecting first. see the image.

Try 'by path'?

the requirement for this macro is, by selecting a single node, remaining nodes should be selected and i want to create a RBE3.

set node1 [hm_getmark nodes 1]

*createmark components 1 displayed

*findloops components 1;

*createmark comps 2 -1;

*isolateonlyentitybymark 2;

 

*createmark elems 1 'by node' $node1;

set elist [hm_getmark elems 1]

*clearmark elems 1;

#filter the plot elem
        foreach id $elist {
            *createmark elems 1 $id;
            if {[hm_getmarkvalue elems 1 config 0] == 2} \
            {
                break;
            }
        }

*appendmark elems 1 'by attached'

 

eval *createmark elems 2 [hm_getmark elems 1];

 

 

#get required node list in order
 set nlist [lremove  [hm_getmarkvalue elems 2 nodes 0] $node]

 

 

please try this........

I think from v2017 you can select nodes by 'edges' so we don't need script to do that
