I´m developing a tool to generate an openFoam wind tunnel case of a wind turbine. I already have the blade geometry constructed, but I'm really new to CFD and parametric meshing. I found some articles where they mention a C topology to mesh the airfoil and also some software (bladedesigner) that mentions a topology named O10H, but none of these has a reference about how to implement these topologies and if there are others. They also do not specify what the best use cases for each one.
Can someone help me to get started making an efficient mesh for my tool?
EDIT: At the end I want to have a domain like the picture below, with other blade orientation, but first I need to define the mesh topology around the blade.
My example Blade:
Some of the mesh topologies that I found:
Bladedesigner O10H topology
Various C topologies
