Sir I am facing a problem in simulating FSW.
The Error message comes as " The Abaqus time increment has become negative?? = -11.606
The Abaqus time increment has become negative?? = -13.927
The executable C:\SIMULIA\Abaqus\6.10-1\exec\explicit.exe aborted with system error code 29539. 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."
