Hi all,

I wanted to ask if anyone has experienced this error before when running the Hypoplastic UMAT (umat_hcea.for) on Abaqus?

“Abaqus Error: 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. ”

I would like to know what can be done to remedy this? I have looked at other forums online such as:

The suggestions there did not help solve the issue for me. I am running Abaqus 6.14-1 on Windows 10.

Thank you,

    I have managed to fix the problem! Turned out that I did not define the 16 state variables of the Hypoplastic Umat in the material properties through Depvar.

    Hence, umat_hcea.for now running smoothly on Abaqus 6.14-1 Windows 10.

    Whenever I am running the umat for clay hypoplasticity, it is getting exited in ABAQUS by fulfilling the criteria testnan=1. It is failing the check – “check whether the strain rate from the ABAQUS is not NAN “. How can I resolve the issue? I am able to run the umat for sand hypoplasticity successfully though!
