Hello, colleagues.
Recently, I have been working on a metal processing simulation with my UMAT in Abaqus. I have outlined the corresponding simulation, but I keep encountering issues that cause the calculations to interrupt. I have provided the details of the simulation. Can anyone help me resolve these issues? The common errors are as follows:
---------- RUNTIME EXCEPTION HAS OCCURED ----------
standard.exe / rank 0 / thread 3 encountered a system exception 0xC0000005 (EXCEPTION_ACCESS_VIOLATION)
Dear Reabet Gion,
this access violation error usually appears when you try to access unallocated or freed memory in your UMAT code . Also, judging by the error, it seems you are running a parallel job in abaqus. if this is the case , try to run the analysis as single core initially for easier debugging and then move on to parallel job submission after having made all the code you have written, thread safe.
