Hello, I'm currently starting a study about two gear set optimization using FEA, looking for the lowest stress on the tooth root fillet, thus providing longer component life.

I would like to understand which is the best way to perform the study. My plan is to start with 2D analysis and eventually, it can turn into a 3D analysis.

Here are two ways that I think it might work:

- Generating a mesh from an existing accurate tooth geometry, and use nodal relocation to find the best node positioning and hence best geometry. Then, to simplify the manufacture process, I can interpolate a curve and get the optimized geometry of the root fillet (the main challenge in this way is how to relocate nodes - I'm not sure if that can be done using APDL);

- Perform a parametric optimization of the involution curve based on the stress results from the FEA (the main challenge in this case is how to model the involution curve from Space Claim or APDL).

Perhaps with the integration of certain tools, such as the Python Language and Libraries, they can assist in the geometry design process or even in the optimization process.

I'm open to suggestions!

Thank you!
