Default Fluent Dynamic Meshing

I am trying to model the water-entry phase of a thin triangular wedge. The way I have created the grid is to divide the flow domain into two fluid zones called "fluid" and "moving_fluid". The "moving_fluid" zone is a small zone adjacent to the wedge, while the "fluid" zone comprises the rest of the domain. Both the "moving_fluid" and "fluid" zones are meshed using the triangular pave method.

I specify the RIGID-BODY movement of the "wedge (wall)" and the "moving_fluid" zone using a udf while defining the dynamic mesh zones in Fluent. I also enable remeshing and smoothing of the mesh.

Even though I have specified that the "moving_fluid" zone moves as a rigid body, while previewing the mesh-motion I see that that triangular mesh within this zone gets smoothed on remeshing. Fluent manual does mention that if the zone is meshed using a QUAD scheme it is not smoothed.

I was wondering if there is a way to selectively tag a zone with triangular elements to prevent smoothing.

Thanks in advance for the help.
