How to remove nodes from a set by usage of tcl

Altair Forum User

Hi everybody,

 

I try to add some nodes to a node-set by usage of tcl like this:

 

*createmark nodes 1 $nodeID
*appendmark nodes 1 'by face'
*entitysetupdate 'NSET' nodes 1

 

This works perfectly!

 

But now I would like to remove nodes inside of a specific box. I tried this but it doesn't work ...

 

*createmark nodes 2 'by box' $x1 $y1 $z1 $x2 $y2 $z2 0 inside 0 1 0

*markintersection nodes 1 nodes 2

*deletemark node 1

*entitysetupdate 'NSET' nodes 2

 

What am I doing wrong?

 

Thx in advance
