Get mid-side node

[Roshan Shiveshwar 8]

Hi,

 

I am trying to create a simple Tcl script, where I should be able to identify the mid-side nodes from the model and put it in a list.  Is there any API to achieve this?

 

Thanks,

Roshan

May we know reason?

 

Which element configs do you have?

This was a code to get elements from set of nodes. I discovered now that the code fails for 2nd order elements because of the mid-side nodes.  Hence, wanted to identify them and avoid them in the calculation.

I remember there is a relevant command but can't find it.

 

Example to get mid side nodes of quad8:

*createmark elems 1 "by config" quad8

set NodeList [hm_getvalue elems mark=1 datanames=nodes]

set MidNodes [join [regsub -all {\{[0-9]+ [0-9]+ [0-9]+ [0-9]+ } $NodeList \{]]

Thanks Tinh,

 

This one is a useful hack.
