Dear all,

 

I'm struggling with a TCL code. The problem is that I need to select and count in automatic way nodes which belong to a specific line.

Usually I have a meshed surface and need to count nodes on one specific line. The line number is always known and stored in a variable.

 

My initial idea to count elements/nodes was following:


 *createmark elems 1 “Which belong to a line” “line no”
 set elemIds [hm_getmark elems 1]
 set numElems [llength $elemIds]

Do you have any ides how to solve that problem?

Thank you in advance.

 

Best regards

Jakub
