Reading Abaqus .fil file

Dear all,

in order to access the last value of my state variable SDV at specific integration points and specific elements, I need to write the SDVs into .fil file in order to be able to read them inside my UMAT at each time increment.

I use the subroutine DBFILE to read the .fil file; the keyword to access the state variables is "5", but I don't know how I can go to the value which has been already written to the current integration point.

Could anyboby help?

Thanking in anticipation,

hadi
