MESSAGE ID : 44
** ERROR: ABNORMAL END
+=============================================================+

How to resolve this error?

Thanks.

    It isn't possible to deduce what the specific error may be from that, just that there was a crash.

    If you can share the model here, or with Altair support, someone may be able to help

    If you want to try and debug yourself, if you have part energies in T01, check to see if a part is getting high energy at the end, you could also try stopping your first engine at just before the crash point (4.88e-4) and then having a second engine file outputting animation files with very high frequency (2e-9, cycle size) and check the animations to see if you can see something blowing up. Your timestep is very small throughout, I guess you must have some very small elements?
