Hi all, i'm trying to use the abaqus 6.12 with the user subroutine (UMAT). I'm sure that the subroutine has not any problems, but the analysis abort soon and the log file  shows this problem:

"Abaqus Error: The executable standard.exeaborted with system error code 1073741819.Please check the .dat, .msg, and .sta files for error messages if the filesexist.  If there are no error messages and you cannot resolve the problem,please run the command "abaqus job=support information=support" to report andsave your system information....etc.."

The  .dat, .msg, and .sta files do not contain any error messages.

It seems that my computer reach the "Memory limit", because the same subroutines applied on a single element run correctly but it dosen't work on more complex mesh. What is the problem?

I tried to run the same input file with the same subroutine in an other computer more performig than mine and the analysis run, but the problem return if i use another mesh with more element than the last one.

I installed on my computer abaqus 6.12, visual studio 2008 and visual fortran 11.1. My OS is windows XP 32bit but the same problems occur on windows7 64bit.
