here is another fact - which I cannot understand:
judging by the graph - the initial velocity of the rigid body increases over a fairly long period of time.

I do not specify this period of time...

ls-dyan somehow determines it itself.....

Nothing is said about this in the documentation... - to be more precise, I did not find anything

hence the question:

and how then can one specify the initial velocity of the rigid body - without the "acceleration time"??

Is it possible to do this at all?

and one more question:

I specify the initial velocity of 1000 mm per second, and here again ls-dyan "acts up"... - the velocity - judging by the graph:

1.1987445068e+03 mm per second

1.0016828537e+01 1.1987445068e+03
