hi

have you linked intel fortran with visual studio and Abaqus?

Thanks Shahram, yes I did. Otherwise I would have received an error during the subroutine compilation, i. e. ifort.exe, right? As I said the run will be completed with no error. The problem is I don't see any contact effect on the pin inside the hole after the run is complete. I added the contact output to my model, but it's still the same condition.

Any comment?

Thanks,

First, you should make sure that your routine UINTER is actually called by Abaqus - just add a

write(*,*) 'called now'

somewhere to the routine (the output should go either to the dat or msg-file and also to the screen if you run interactively). You can also use this to find out what values of rdisp are passed if the routine is called.

In addition, changing the lopenclose-variable should trigger a severe discontinuity iteration. Does this actually happen? (look at the sta-file)

Alternatively, try to create a model with only a very small number of elements or try to use your UINTER together with one of the example files from Abaqus in the verification manual.

Finally, in Fortran you should not write

-2.65258*10**6

but

-2.65258*E6

in my opinion you should write the parameters concerned with the contact to a file or screen to be able to see if they are changing in the steps you have given. for example you can ask contact forces as the output and monitor it by writing to the file or screen. in this way you will be able to see if anything is changing in the early steps.

Thanks a lot, Martin and Shahram. I will use your useful tips to see if I can sort out the problem then I will update you.

Cheers,

Hi guys,

I think i have similar problem.

I run and test a simple subroutine to display hello world to an input file (riserdynamics_airy_disp.inp; attached below) from abaqus manual and managed to print"Hello world"

the subroutine;

SUBROUTINE DISP(U)

C

INCLUDE 'ABA_PARAM.INC'

C

WRITE(*,*) 'Hello World'

RETURN

END

However, when I tried to my model that I developed in Abaqus cae (2Dwearsub.inp;attached), it  was completed without printed the hello world.  I cant figured out what are the problems.

Any comments??

Thanks Hans Schmidt;

I had tried  a few combination of the user properties and depvar value. However, the input analysis exited with an error.

the input file added

** INTERACTION PROPERTIES

**

*Surface Interaction, name=IntProp-1 user, properties=10, depvar=10

1.,

1, 10, 10

*Friction, lagrange

0.15,

*Surface Behavior, no separation, penalty

any suggestion? (here are the files related)
