Hi,
I am going to apply Periodic boundary condition on my model in abaqus. I am using Explicit solver for my model. However, after submitting the job, I am getting errors like below, while in the .Dat file there is no trace of error. Could you please let me know the issue? 

Run package.exe
*** ABAQUS/package rank 0 received the ABORT signal

*** ERROR CATEGORY:  PACKAGE
