Retrieving of Nodes.

Altair Forum User

Hi all,

 

can anyone help me in retrieving the nodes when saved through 'lappend' command

 

command used:

 

set saved [hm_getmark nodes 1]

 

set nn [lappend nn $saved]

 

Result:

 

nn_layer = {251497 251498 251499 251500 251501 251502 251503 251504 251505 251506}, llength = 

 

1

nn_layer = {251497 251498 251499 251500 251501 251502 251503 251504 251505 251506} {253243 

 

253244 253245 253246 253247 253248 253249 253250 253251 253252}, llength = 2

 

i want to retrieved the all nodes but only two nodes are retrieved from different layer.

Hi there!

 

use the following:

 

 set saved [hm_getmark nodes 1]
 set nn [lappend nn $saved]
 set nn [ join $nn ]
  
 foreach n $nn { puts $n}

 

cheers!

 

edit: just to explain what you where doing. You where appending a list o another list. Each of the items of your list was another list.

Hi there

alternatively using 'eval'

set nn [eval lappend nn $saved]

Hi Cesar and Tinh,

 

thanks for helping.

 

now every node is acting as different entity and able to retrieve all at once when needed.

 

' set nn [ join $nn ] '

 

thanks

Adams.
