Zero state variables passed by USDFLD

Zero state variables passed by USDFLD

Zero state variables passed by USDFLD

(OP)
Hi, I am trying to use some quantities in my UMAT such as pore pressure, strain energy, coordinates, etc., so in order to get access to them I am using USDFLD which calls GETVRM to get those values at the integration points, and assign them to solution dependent state variables STATEV. But these are always zero when I plot them or get them using write statements. Any hints on what I'm not doing right? I'm so frustrated!! Thanks!

RE: Zero state variables passed by USDFLD

(OP)
An additional note:
All the ARRAYS in general are zero-valued in USDFLD when I write them to .dat file:

      CALL GETVRM('SINV',ARRAY,JARRAY,FLGRAY,JRCD,
     $     JMAC,JMATYP,MATLAYO, LACCFLG)
C     stress invariants (MISES, TRESC, PRESS, INV3)     
      JERROR = JERROR + JRCD
      FIELD(1)=ARRAY(1)
      FIELD(2)=ARRAY(3)
      WRITE(6,*),"MISES - ARRAY(1)",ARRAY(1)
      WRITE(6,*),"PRESS - ARRAY(3)",ARRAY(3)
