In a vumat, how to get the orientation axes specified in an abaqus model/inp file ?

Hi everybody,

I have searched on the online help of Abaqus for this syntax problem but cannot find the solution...

Let's consider that I define an orientation "o1" for my material "m1" in my model/ my inp file. How to do in order to read this orientation "o1" in a vumat file ? In my vumat it would be something like:

axe1 = "read axe1 of o1 in inp file"
axe2 = "read axe2 of o1 in inp file"
axe3 = "read axe3 of o1 in inp file"

I want to realize calculations based on this orientation.

I hope that some of you may help... Thanks in advance and have a good day !

Lisa.
