Mesh
The following video shows how to create a mesh for the 2D geometry. We stick with the default "Q8" elements (eight nodes per element including mid-side nodes). The element edge sizes are controlled by inserting a "face sizing".

We improve the mesh obtained above by refining the mesh in the transition region between the larger and smaller cross-sections where stress concentration is expected. We do so by:
- Decreasing the _Curvature Normal Angle_ which sets the maximum allowable angle that one element edge is allowed to span
- Decreasing the _Min Size_ which sets the minimum allowable element edge size
