Dear Reno,

Thank you very much for the reference papers.

I am interested in the added mass forces arising before the collision event and its effects on the fluid-structure interaction model. Boundary layer and drag effects can be neglected. 

I found this following guideline document from the LS-DYNA aerospace working group.(https://awg.ansys.com/MGD). In page 75 it is mentioned that the ALE solver is not well suited for longer duration problems. I would like to know if this is regarding the numerical stability of the solutions.

Regards

Abhemanyu
