Dynamic mesh mesh deterioration
 
Hi,

I am using Fluent's dynamic meshing around a deforming airfoil , however the Minimum Orthogonal Quality goes way under 0.01 when it is deformed.

I checked the cell where this low quality is but it looks ok.

I am using spring based smoothing and remeshing with a quadrilateral mesh.

Does the re-meshing handle quadrilaterals?

Will this low quality affects the flow and is there any method to improve the mesh?

Thanks
