Mesh size for fatigue calculation in ansys according to DNV

Mesh size for fatigue calculation in ansys according to DNV

Mesh size for fatigue calculation in ansys according to DNV

(OP)
Hi
I am currently modelling a wire sheave. The only thing left to do is fatigue analysis. Iam not very formiliar with fatigue calulations.
I read up on DNV RP C203 and now i need some hotspot stresses from my ansys calulation. In DNV it states that the element mesh size should be txt (where t is the thickness of the plate). My concern is that the plate will be to taken to stiff whith this mesh size. But with a smaller mesh i get a singularity at the edge.
Do anyone have any suggestion on which mesh size i should choose, and if there is any theory supporting that i choose a mesh size of 0.5t? the sheave is 25mm thick.

Best regards
