sequential node numbering in meshes
 
Hello,

Some of the meshes generated by ICEM do not have sequential node numbering. For example, in one of my nastran files (see attached), the node numbers are continuous upto 11 and then jump to 15. Is there a way to constrain the node numbers to be continuous while meshing in ICEM?

Hi Mirunalini,

I have the same problem but import the geometry as .prt file from NX. Did you find any solution how to control the node numbers?

An other way for me to solve it to use
[CODE]
ic_hex_select_nodes 1 all m FLUID node_numbers
[\CODE] which returns all the node numbers that are connected to the part "FLUID".
An other form of this function is to locate the node in a specific point, coordinate, instead of returning all nodes. The function looks like this from the programmers manual
[CODE]
ic_hex_select_nodes num method index_range m parts
[\CODE]

and should in my case be:
[CODE]
ic_hex_select_nodes 1 inpoly {369.13875 211.52306 -1.1669954e-10} m FLUID node_numbers
[\CODE]
However this doesn't work, I'll get the error "Error: Error reading polygon coords"

Do you know how to solve this? Or control the numbers of the nodes?

Thank's for your assistance!

Hi friends,

I am trying to answer the same question of this thread's title. Could anyone help to understand blocking vertex numbering? It seems doesn't have any sequential rule.

Thank you in advance.
