Mesh distribution

Hi, i have some troble for getting coherent results in a keyseat simulation. I think this is because of the mesh.

let me show you what i mean:

standard mesh with control of 0.5mm, relation 1.2, the mesh is not even(for me)

based on curvature mesh:( i think it is a better. the thing is that i only want to focus o the end fillet, not the whole part and i can´t do it with this tipe of mesh)

minimun size of element: 0.5mm

number of circles: 36

relation: 1.2

What else can i do?
