Hello,

I am trying to apply infinite elements to model non-reflecting boundary conditions.
The problem deals with wave propagation in ground, and I am trying to model infinite conditions for the ground in 3D.
But, I face an error as follows:

************************************************** **************
Abaqus Error: The executable /usr/apps/isv10/abaqus/6.7-1/exec/package.exe
aborted with system error "Illegal memory reference" (signal 11).
Please check the .dat, .msg, and .sta files for error messages if the files
exist. If there are no error messages and you cannot resolve the problem,
please run the command "abaqus job=support information=support" to report and
save your system information. Use the same command to run Abaqus that you
used when the problem occurred. Please contact your local Abaqus support
office and send them the input file, the file support.log which you just
created, the executable name, and the error code.
Abaqus/Analysis exited with errors

Is there anyone who has experience working with infinite elements in 3D?
Previously, I have worked with infinite elements in 2D by editing the *.inp file, but I am wondering if I can follow the same procedure in 3D.
Any advice is highly appreciated.

Regards,
Ramin
