Hello,

I have a txt-file which looks like this:

1 2.
2 2.
3 2.
........
5758 4.
5759 4.
5760 4.

where 1st column - elem number, 2nd -some parameter

I'd like read data from text file into subroutine SDVINI

and I need use this data for further purposes in UMAT subroutine.

SUBROUTINE UMAT whitout SDVINI works ok, but with SDVINI gives an error in Abaqus....

I think it's because I'm not correctly written code SDVINI subroutine.

please check my code

SUBROUTINE SDVINI(STATEV,COORDS,NSTATV,NCRDS,NOEL,NPT,LAYER,KSPT)
C
INCLUDE 'aba_param.inc'
C
DIMENSION STATEV(NSTATV),COORDS(NCRDS)
real, dimension(5760,1) :: RHON

STATEV(7) = 0
IF (STATEV(7).eq.0) then

fname='D:\d113.txt'

Open(66,file=fname,form='formatted',status='old')

READ(66,*) RHON

STATEV(1)= RHON

CLOSE(66)
ENDIF


RETURN
END

and in UMAT i need use next eq.:

EMOD=STATEV(1)**2.5

so i need use in umat parametr from txt-file

but i dont know how to read correctly data from file

I would really happy if you can help me in this.
