SIGINI SUBROUTINE CAN BE IMPLEMENTED IN CAE????

[leo81]

Hi guys,

is it possible to use SIGINI in Abaqus CAE?
if yes....how???????????????

I read on the Abaqus Analysis User's Manual 19.2.1 that:
"ABAQUS/CAE Usage: Initial stress is not supported in ABAQUS/CAE"

but it is not clear...could please someone explain to me???

thanks a lot!!!!

You have to use the keyword editor to insert
*INITIAL CONDITIONS, type=STRESS, USER
just above the definition of the first *STEP

Then attach the subroutine file containing SIGINI to the job, if you submit the job from CAE.

How can I attach the subroutine file containing SIGINI?
where could I find information about the use of subroutine?

thnaks a lot

Maybe I need fortran?

"is it possible to use SIGINI in Abaqus CAE?"...
Yes, it is.

You will need:
1. Install Visual Studio (I use VS 2005)
2. Install Intel Fortran compiler (I use Intel Fortran 9.1).
3. Adjust environment variables so Abaqus can "see" VS and Fortran. (see for example:

4. Search in Abaqus help files an example of SIGINI. Change it as you need.
5. From CAE, go to Model -> Edit keywords and do what Xerf said
6. Edit your job and specify the file that contains sigini sub.

good luck
