Ordered node set in TCL

Hi everyone

I have a macro that I am writing to automate a repetitive task. I have this almost complete, however I am stuck on one thing at the moment.

I am using HM with LS-DYNA.

I have a nodal path which I have used to define an ordered node set (say node ids 25 26 27 10 50 52 60 61). I have verified that the card was generated correctly with the nodes in the correct order.

This set was copied to mark 1 (*createmark nodes 1 ....). Then I used hm_getmark to place the nodes into a tcl list.

However when I reviewed the tcl list, it was sorted from lowest to highest (eg using the above numbers: 10 25 26 27 50 52 60 61).

Any suggestions for getting the original list order into tcl. My code is below:

#=========================

*createmark nodes 1 'by set' set_name

#hm_getmark entity_type mark_id ?panel_sensitive?

set node_Ids [hm_getmark nodes 1]

#=========================

I assume that the problem is that the hm_getmark is the wrong command to use in this case, and this is where the list is sorted.

Thanks for any comments and suggestions.

Regards
