Dear community.
I am trying to create a mesh for this geometry: a cone that goes from diameter D1 to diameter D2 with length L1, which is attached to a tube with diameter D2 and length L2. Dimensions are not important. Y is the axis of revolution.
Right now I am using algorithm NETGEN 1D-2D-3D with hyphotesis NETGEN 3D parameters.
It does work but the mesh is not simmetrical. Since I need a symmetrical mesh, which algortihm do you suggest? Are there are any good tutorial online?
Thank you for your help.

My problem is somewhat similar to yours. To solve it, I recommend watching this video. In it, the author creates a symmetrical mesh by rotating it for use in OpenFOAM.
Parametric geometry and mesh using Salome 9 for OpenFOAM 2D case
it is normal that it is not symmetrical, what you are doing is more like hopping to get a symmetrical mesh out of snappyhexmesh. netgen does not ‘recognize’ that the geometry is symmetric, so it will not follow this.
what you can do is, mesh half of it and then mirror it.
