Understanding node numbers 1

[Timusop]

Hello all,

I am trying to clear up my understanding of node numbers for parts in Abaqus. I have two parts. One has node number 1-54 and the other has node number 1-63. I would like to make reference to the node numbers in a subroutine, but how can I distinguish between the part node numbers? i.e. Are these the local node numbers above and should there be "global" node numbers I can find out somehow?

Thanks

Hi,

Abaqus uses different node/element numbers (internal id) compare to ids in a inputdeck (user id) during calculation.
To obtain internal numbers you have to use GETPARTINFO or VGETPARTINFO.
Some of the subroutine (e.g. VFRIC) use different node ids then internal or user numbers.
In this case one of subroutine dummy arguments usually is additional array with references between subroutine ids and users ids.

Hi,

You can make abaqus CAE write your input files such that only one single part is produced. For example you have two parts, the first part goes from node 1 - 54 and the 2nd from 1 - 63. You can tell abaqus to combine your parts such that the first part will have nodes 1 - 54 and the 2nd part will have nodes 55 - 138.

So now you have 2 parts and the node numbering does not overlap.

I think this is much easier. To make abaqus join different parts together go to your env file in the site folder of the install directory and copy the following in at any location in the file.

cae_no_parts_input_file=ON

Now there will be consecutive node numbering

Hope this helps
