How to know actual nodal number in UEL

[mapi]

Hi,
In UEL, Abaqus, we don't know the actual nodal number in the element, right?

For example, one element has the following four nodes: 3, 4, 5, 8. Then in UEL, COORDS(1,1) denotes the coordinate of first degree of node #1, that is node with actual number 3. Now I want to know the actual nodal number 3, 4, 5, 8, how?

Thanks.

I am not familiar with UEL. However, I took a quick look at the documentation after reading your post.

A possbile solution you would try is to write the connectivity information in a text file.

Read the connectivity information in the beginning of the analysis.

You can use for example UEXTERNALDB, to load the connectivy info in a 2D array placed in a COMMON BLOCK .

Write a subroutine to look up element labels in the connectivity array and return the nodes labels.

Call that subroutine when you need it from UEL using
JELEM - User-assigned element number

Thanks. I have worked it out just by reading a txt file within all the element information in UEL.
But maybe it is also OK or even simpler to use UEXTERNALDB.

call GETPARTINFO from within your user subroutine.
