"How Are Node Orders Defined in an Element Retrieved via hm_nodelist?"

asdfsdfasdfasdfasdf

set nodelist [hm_nodelist $elemid]



set n1 [lindex $nodelist 0]


set n2 [lindex $nodelist 1]


set n3 [lindex $nodelist 2]


set n4 [lindex $nodelist 3]

I have a question: when I retrieve the nodes of an element like this, how is the order of the nodes determined?

For example, does n1 always correspond to a specific location in the element, such as top-right, bottom-left, etc.? Or does the order depend on element orientation, ID, or something else?

Hi,

The list will follow the element grid point identification. You can find more information in this link from the help: https://2024.help.altair.com/2024/hwsolvers/os/topics/solvers/os/chexa_bulk_r.htm?zoom_highlight=CHEXA

So if you have defined the n1 = the first item in the list, the N1 will be the G1
