Dear all,

We want to model a pressure vessel using WCM (Wound Composite Modeler). We have built a model  by following  the instructions in user manual and examples. For post processing, UVARM subroutine was generated by WCM Plug-in. Then we have run our input file with UVARM subroutine; however, we have encountered an error as expressed below;

" Abaqus Error: The executable Standard with system error aborted with system error "illegal memory reference". (signal 11). please check the .dat, .msg, and .sta files for error messages if the files exist." 

Since we have no internet connection at our computer where input files are run, we can not generate system information to report. When we search the error on the internet, common offer for solving problem is avoiding parallelization but we have tried it with one cpu and we have encountered with same problem again. 

By the way, to compile and run our model, we made some changes in UVARM subroutine file. It is that logical definitions were changed into integer definitions (e.g. false->0 and true->1) because we use gfortran as compiler.

Could you please inform us about the possible solutions to our problem? We're looking forward to your reply. Thank you in advance.

Best Regards,
