Hi everyone
When I use sanisand model in abaqus , This error is seen
Can anyone help?
Other subroutines work well for me
Is it possible for my input parameters to be wrong?
I tried to use the proposed parameters of sanisand (pdf)

The executable standard.exe aborted with system error code 1073741819. 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.

    Hi mj,

    I have seen this error code when the umat exits the computation that is triggered when predefined conditions in UMAT are met (e.g., the stress point is outside the yield surface). I think the best way to find what is wrong is to let your umat print relevant information to a given log file when an error occurs

    Hope this can help.

    G0 looks to me a 1000 times to big.
    G0 is a dimensionless parameter
    Shear modulus is calculated as below (copy past form Fortran code)
