Hello,
I'm using a vumat in Abaqus and i'm storing data associated to each Integration Point present in my model. For the time being, I scale my array to a given large size, say M(10000).
I would like to know if there is a function that i could use in my vumat to directly access this total number of IP. I would then be able to size accordingly my array M (dynamic allocation).
Best regards,
Joël
Dear Joel,
you could try to use a common block variable,
this is to share information between subroutine calls:
COMMON/UMPS/NumberIPs
Then in the vumat at the first time step, you first initialize NumberIPs to zero.
At the second time step (only) you do:
NumberIPs = NumberIPs + 1
and this statement must be protected using MutexLock/MutexUnlock to avoid multiple processors updating NumberIPs at the same time.
At this point your variable NumberIPs will be the total number of IPs that are calling the VUMAT. Of course if you are using user material combined with non-user materials, this will not work.
Best Regards,
Nicolò
Variables passed in for information
nblock
Number of material points to be processed in this call to VUMAT.
