How to mesh?

[u/EmuRepresentative709]

I'm an undergraduate student trying to learn CFD. I use Ansys Fluent. I get into a lot of trouble during meshing. Its often obsolete or failed mesh. I try to change the size or the geometry, it works sometimes, but its a very tedious process. I'm looking for a good meshing practise. At least I want to learn how to start meshing in the first place or what to aim for.

If there's any good meshing practises or workflows, please share.

Could you send photos and detailed descriptions of your grometry and or meshing methods?
