Re: [Q] Problem creating data files in ABAQUS/Explicit user subroutine VUMAT

Dear Wim,
I am using the syntax
open(16,file='path and filename',position='append')
write(16,*) Lot,po(Lot),pu(Lot)
in Abaqus Standard. I advise you to post your question
in the Abaqus mailing list :
formatting link

Good luck,
Frank
