Predefined stress field (Geostatic) with UEL subroutines

Hello everyone:

I am developing an UEL in which the initial stress field matters (stress-dependent), and i was wondering: how do i transfer the predefined stress field from Abaqus to my UEL ? is it through the PREDEF argument? This problem didn't rise when i was using UMAT subroutines, because the predefined stresses were transferred from abaqus to the user subroutine through the stress argument ie :UMAT(stress,....)

Thanks,
