Create force on line

Hello, i just start to use Tcl script on hypermesh.

 

I've a script who create a simple geometry and mesh on hypermesh.

And i need to create boundary conditions.

 

with the commande file I've :

 

*startnotehistorystate {Created Force }
*createmark nodes 1 1-19 1920-1945 4553-4559
*loadcreateonentity_curve nodes 1 1 1 -0 -0 50 0 0 50 0 0 0 0 0
*endnotehistorystate {Created Force }

 

The problem is that the nodes are not always the ame (depend on my geometry).

Can I create boundary conditions without the number of the nodes ? Like with lines ?

Something like :

 

*startnotehistorystate {Created Force }
*createmark nodes 1 Line 3
*loadcreateonentity_curve nodes 1 1 1 -0 -0 50 0 0 50 0 0 0 0 0
*endnotehistorystate {Created Force }

 

Thanks

Sorry i'm really a beginner with TCL.
