Better Resolution of Time

Better Resolution of Time

Better Resolution of Time

(OP)
Dear friends,
I am doing a basic impact problem in which a deformable ball (made of Aluminum) is being dropped onto a rigid flat plate from a height under the influence of gravity.

My primary aim is to resolve the impact time to the nearest milli-second.

My approach to this is by plotting the displacement of a defined set of nodes throughout the time step. I have made sure that these are the only possible nodes in contact during the impact.

I have tried to resolve the timing to the nearest deci-second by plotting the graph of disp vs time.
Is there any way to obtain that level of precision for the impact time?

I have read about mass-scaling, but I don't want to change the inertia properties of the ball and decided against using it.
Will time scaling help in this scenario?

Any help is highly appreciated.

Regards,
Murali
