Selecting every second node on face - tcl

Hi,

I am a very beginner in tcl so I have decided to share my doubts.

In my model I have to distribute a force using RBE3 element. The inconvenience is that the number of independent nodes is limited to 1000 in Hypermesh and I have much more nodes on the face I want to apply load to. Thus, I am wondering if it is possible to write a tcl macro that selects every second (every third, etc.) node on a given face.

I would appreciate any help.

    I don't know what do you mean 'every second, every third,...'?

    Mathematically, if you take only one node for every two (or three) nodes you can got under limitation of 1000 nodes, but nothing warranty that taken nodes present correctly mechanical behavior of structure.

     

    Share your HM model? I would like to have a look at your mesh.

    If distribution is equal then it's better to do it by pressure load
