Subroutine ORIENT

[hamidfarivar]

Dear All,

I'm totally new in Abaqus subroutines and currently I intend to use the subroutine ORIENT. The question is how can I assign various material orientations to different sections of a body. More clearly, I need to define two different material orientations to a bisection solid via ORIENT coding. I managed to do it in the Abaqus/CAE, but I need to perform the same work by the mentioned user subroutine.

I appreciate any advice in advance.

What exactly are you trying to do? Have you looked into the discrete orientation option in CAE?

I have a model which contains two sections. I'm simply trying to specify certain orientation to each section through the ORIENT subroutine. As it's described in the manual, generally, it should be like this :

SUBROUTINE ORIENT(T,NOEL,NPT,LAYER,KSPT,COORDS,BASIS,ANAME,
1 NNODES,CNODES,JNNUM)

include 'aba_param.inc'
C
CHARACTER*80 ANAME
DIMENSION T(3,3),COORDS(3),BASIS(3,3),CNODES(3,NNODES)
DIMENSION JNNUM(NNODES)
C
defining the T array should be implemented here
C
RETURN
END

now here the question arises that how it's possible (which commands should be used?) to assign two different orientation to two sections in the above subroutine, one for section 1 and one for the another section.

Why can you not do in CAE? Unless I am missing something, it seems pretty straightforward.

Thanks for your reply. I do can in the CAE, I'm just wondering how is it doable in ORIENT.

I am still not sure what the goal is. If you can accomplish your goal in CAE with minimal effort, thereby saving time/money, then why worry about a subroutine? Like I said above, spatially varying orientation is possible to do using discrete orientation option in CAE.
