ABAQUS/Explicit Time scaling

[BigLeon]

I am using ABAQUS/Explicit for structural impact problem. Unfortunately, the model become instable soon after contact. I guess there should be a user defined scale factor to control the time step like LS-DYNA. I searched the keyword manual but unsucessful. Could somebody tell me how can I control the time step.

I think you may be looking for &quot;*Fixed mass scaling, dt=<time increment>&quot;
