Drop Test in Transient Structural

Hello,

I am trying to simulate a drop test whereby a cylinder falls onto a curved model as shown below.

I am using a transient structural system, with a standard earth gravity applied.

Using velocity equations, I have calculated the time of impact to be 0.142 seconds after the cylinder is dropped.



Is transient structural the best way to solve this?

Currently, my results have not shown any impact between the falling body and body taking the load. How can I fix this?

Thanks.

Hi pnomura,
Generally, in a case like this, you would want to give your dropped object an initial (calculated) velocity and move the object to within close proximity of the surface to be impacted. That will ensure that the contact search algorithm has a good chance of finding the contact geometry.
