So, I came up with a brick wall when creating a field variable with third deviatoric stress tensor invariant , J3, dependency.
The closest approach should be calling this invariant with subroutine SINV (Abaqus subroutine reference guide), but I don't understand why this invariant is not...
You should always run (as I have experienced) abaqus subroutines through command prompt, with 'abaqus job=jobname.inp user=subroutine.f(or .for) interactive datacheck', if it gives you errors, it should be easily detected, if it shows THE ANALYSIS HAS COMPLETED, and your results are still zero...
So, I re-wrote the subroutine and apparently fixed it. ONE TIP FOR GUYS WHO ARE TRYING TO GET INTO ABAQUS SUBROUTINES: Don't trust all the examples put into the verification guide and subroutines contained in the files, they are not good for learning purposes. You should start with the basics...
I tried to run it without subroutine, and it seems to be running fine.
although, something about that .dat file bothers me.
it says:
***WARNING: THE *USER DEFINED FIELD OPTION HAS BEEN USED, BUT THERE ARE NO
USER-DEFINED FIELDS ACTIVE IN THE MODEL. USER-DEFINED FIELDS MAY...
Hello guys!
So, I've been facing a wierd error during explicit analysis with a VUSDFLD subroutine. So long I've trying to define my displacement at failure in '*Damage Evolution' as a function of a field variable.
As running the datacheck with a subroutine VUSDFLD, the datacheck shows...
Hello, guys!
I've been trying to write a script to express the Lode angle (Polar deviatoric angle), as defined here: Ductile damage criterion wit lode angle dependance (Abaqus Analysis User's Guide).
Shortly I'd like to express the variable defined in the link, ξ (in range of -1<ξ<1) in a...
