need your help: extract Ids from elements

Altair Forum User

dear for all

i need to extract nodes from several comp like green elements in ordered way:

the idea is to extract nodes from begin 1 to end 1 and from begin 2 to end 2 separately

i used  [hm_getvalue comps id=$compid dataname=nodes.id] --> no ordred Ids 

any propositions?

thx

I don't if there's a function to do that quickly.

If not, you can build a ordered list yourself with Tcl.

I guess, if hm generates free edges, it will create them ordered

so try:

*createmark elems 1 'by comp id' $compid

*findloops elems 1

*createmark elems 1 'by comp name' ^loops

set OrderedNodes [hm_getmarkvalue elems 1 nodes 0]

puts $OrderedNodes

From version 2017 please try this command:

hm_formnodelistsfrommark

 

Or command:

hm_getedgeloops

thank you for your reply,

for the first post: it is equivalent to: hm_getvalue comps id=$compid dataname=nodes.id

for the second we use version 13 or 14

i'm trying with  *markintersection

'for the first post: it is equivalent to: hm_getvalue comps id=$compid dataname=nodes.id'

 

Are them output ordered?

As I tested, they are.

yes they are but not as we wish :

in this capture below we show how we want extract ids in two different lines

thx

you can extract them by 

set index1 [lsearch $nodelist 353389]

set index2 [lsearch $nodelist 352605]

set ligne1 [lrange $nodelist $index1 $index2]

set index3 [lsearch $nodelist 364500]

set index4 [lsearch $nodelist 364593]

set ligne2 [lrange $nodelist $index3 $index4]
