How to know actual nodal number in UEL
How to know actual nodal number in UEL
(OP)
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.

RE: How to know actual nodal number in UEL
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

But maybe it is also OK or even simpler to use UEXTERNALDB.
