Adding "standard earth gravity" to an explicit analysis causes large energy error

Hi,

I am running an explicit simulation in Ansys explicit, everything runs OK and the solve process finishes, but when I add a "standard earth gravity" BC to all bodies the analysis crashes at an early stage due to a large energy error.

Anyone knows why adding gravity causes this?


Thanks.
