Title: Node Sequence error
Post by: ad10 on August 18, 2021, 01:58:42 AM

Dear all,

I have a user element subroutine based on anticlockwise the node sequence which works perfectly fine in FEAP 8.3 but it gives an error of reverse node sequence in new FEAP 8.6, Any suggestions on how can I use this element without changing the element code.

Thanks in advance.

What is the element type and nodal sequence?

I am using a 4-node CZM element, in which the node sequence is as follows
!   2----3   
!   |      |
!   1----4

In FEAP 8.3 it works fine with block mesh in reverse order but that reversed order mesh is not supported in FEAP 8.6, I am getting error as "To correct reverse node sequence on block"

If you use command CHECK FEAP will recumbent.  But you should change sequence to what manual has given.

Thanks, Professor. I made changes in the code as per the manual.
