Linking Abaqus 6.14-5 with Intel Parallel XE 2013 with VS 2010

 

I have been having trouble linking Abaqus with the compiler. I used the following tutorial to link the softwares: 

https://www.youtube.com/watch?v=ImWUFZAKlr4.

I'm using Abaqus 6.14-5 with Intel Parallel XE 2013 with VS 2010. The UMAT code is:

      SUBROUTINE UMAT(STRESS,STATEV,DDSDDE,SSE,SPD,SCD,
     1 RPL,DDSDDT,DRPLDE,DRPLDT,
     2 STRAN,DSTRAN,TIME,DTIME,TEMP,DTEMP,PREDEF,DPRED,CMNAME,
     3 NDI,NSHR,NTENS,NSTATV,PROPS,NPROPS,COORDS,DROT,PNEWDT,
     4 CELENT,DFGRD0,DFGRD1,NOEL,NPT,LAYER,KSPT,KSTEP,KINC)
C
      INCLUDE 'ABA_PARAM.INC'
C
      CHARACTER*80 CMNAME
      DIMENSION STRESS(NTENS),STATEV(NSTATV),
     1 DDSDDE(NTENS,NTENS),DDSDDT(NTENS),DRPLDE(NTENS),
     2 STRAN(NTENS),DSTRAN(NTENS),TIME(2),PREDEF(1),DPRED(1),
     3 PROPS(NPROPS),COORDS(3),DROT(3,3),DFGRD0(3,3),DFGRD1(3,3)
     4 JSTEP(4)
C     ELASTIC USER ROUTINE
      PARAMETER (ONE=1.0D0, TWO=2.0D0)
       E=PROPS(1)
         ANU=PROPS(2)
      ALAMBDA=E*ANU/(ONE+ANU)/(ONE-TWO*ANU)
      AMU=E/(ONE+ANU)/2
          DO I=1,NTENS
           DO J=1,NTENS
           DDSDDE(I,J)=0.0D0
           ENDDO
          ENDDO
      DDSDDE(1,1)=(ALAMBDA+TWO+AMU)
      DDSDDE(2,2)=(ALAMBDA+TWO+AMU)
      DDSDDE(3,3)=(ALAMBDA+TWO+AMU)
      DDSDDE(4,4)=AMU
      DDSDDE(5,5)=AMU
      DDSDDE(6,6)=AMU
      DDSDDE(1,2)=ALAMBDA
      DDSDDE(1,3)=ALAMBDA
      DDSDDE(2,3)=ALAMBDA
      DDSDDE(2,1)=ALAMBDA
      DDSDDE(3,1)=ALAMBDA
      DDSDDE(3,2)=ALAMBDA
      DO I=1,NTENS
       DO J=1,NTENS
       STRESS(I)=STRESS(I)+DDSDDE(I,J)+DSTRAN(J)
       ENDDO
      ENDDO
      RETURN
      END

 

The error message is shown below:


Abaqus 6.14-5

Can you please help me figuring out if my UMAT file is wrong or the compilation is the problem.

I tried this UMAT as well, from Abaqus documentation:

      END

And I got this error message:

Error in job Job-4: Problem during linking - Abaqus/Standard User Subroutines.   This error may be due to a mismatch in the Abaqus user subroutine arguments.   These arguments sometimes change from release to release, so user subroutines   used with a previous release of Abaqus may need to be adjusted.

In your first code, you are missing a comma between DFGRD1(3,3) and JSTEP(4).

As to your second code, I do not know what Abaqus probably is complaining about. That, however is not a compiler or Fortran issue, and you need to take up the question in an Abaqus support forum. Check that the number and type of every one of the arguments to the subroutine matches what Abaqus expects. I have seen 37 arguments some times and 38 at other times, so the number may well depend on the version of Abaqus being used.

Once you fix the first code, compilation will succeed, but you will probably see the same linker error as with the second one.
