VUEL error - (ABAQUS/package rank 0 encountered a SEGMENTATION FAULT)

[g.alshamsi]

Dear All,

I'm trying to run a test model using a user-defined element in explicit (VUEL). The test model involves performing displacement controlled cyclic load on a single element pinned at one end and free at the other (load is applied at the 2nd node). The VUEL in question was retrieved from the literature (MSc thesis) so I'm assuming the formulas/math/logic is correct. Please be aware that I am fairly a beginner when it comes to programming so the edits I did to the code were purely syntax to fit fortran77 language (code runs from columns 7-72 etc,)
After running the model from the command window, I got the following errors:

*** ABAQUS/package rank 0 encountered a SEGMENTATION FAULT

*** ERROR CATEGORY: PACKAGE

My main issue is that I don't know where and how to start debugging the VUEL. The .dat file doesn't show any errors so I have no idea if it's a code error or something else.
Does anyone have any experience with this type of error? I have previously ran some models with VUMAT and it worked fine so the error is not a compiling issue. I have posted a screenshot of the command line in the post.

I can provide more info if its necessary, thanks for reading.

Cheers,

What about the other output files (msg, sta) - did you check them for error/warning messages ? The segmentation fault error is very general while (V)UEL subroutine is probably the most complex one. So it's likely that there's an error somewhere in the code and you should check it carefully.

The .sta file is blank, and for some reason the .msg file is not getting printed.
