Default Issues with dynamic meshing

I am working on a 2D problem where you have a beam like structure inside a square enclosure. The beam is fixed at one end and oscillates up and down(I used rigid body motion UDF to do this). But the dynamic meshing isn't working properly when I use rectangular elements near the beam. It seems to work reasonably well when I have triangular elements near the beam. But the Gambit boundary layer meshing option allows only rectangular elements near the boundary. So how do I make my model work for rectangular elements also?

Also I am confused about which dynamic mesh algorithm(Smoothing, Layering, Remeshing) I should be using..I would be happy if somebody can explain about this also.

what is the configuration you have for the dynamic mesh parameters? are you using layering accompanied by smoothing or remeshing?
If you are only using layering, try typing
define/models/dynamic-mesh-controls <enter>
define/models/dynamic-mesh-controls/ sp <enter>
define/models/dynamic-mesh-controls/sp/soas <enter>

this will "activate" the layering option for the structured mesh.
