Default How to overcome the oscilation in dynamic mesh

hi,

I am a new one to dynamic mesh. my problem is simple. There is a beam blew in air and the motion of the beam in the next time step is calculated basing on the result in the current time step. Now, the difficulty is that I found strong oscilation in the force on the beam and after several time steps, calculation blew up.

Any advice will be appreciated. thanks in advace.

I've found that the dynamic mesh routines are very sensitive to time step size, so try making your time step much smaller.
