Hypermesh for Moldflow: how to mesh fillet with specify # of element along the curve

I tried to create surface mesh for one of my plastic. It has many fillets, and they are important for Moldflow analysis.
I want to using QI optimize option (inside Automesh) to mesh a group of fillets, but mesh not capture the curvature.
Is that a function in Hypermesh can tell the mesher to mesh fillet surface with specify # of elements along the curvature? (ie: I want 3 element along the curve of a fillet with radius of 0.5mm, at the same time, I want my global element size target to be 1mm.)
Thanks.

    Ryanzhao,

    you can use the interactive mode in automesh to adjust the necessary element size for a particular fillet/surface

    See HyperWorks Desktop Applications > HyperMesh > HyperMesh Tutorials > Meshing > 2-D Elements:
    HM-3100: AutoMeshing
    Step 6 - specify a new element density along surface edges.

    curved surfaces are best meshed using the deviation algorithms,
    see - HyperWorks Desktop Applications > HyperMesh > HyperMesh Tutorials > Meshing > 2-D Elements:
    HM-3120: 2-D Mesh in Curved Surfaces
