Hexmesh of a hemisphere

[anton]

Hi,

I am trying to mesh a hemisphere using a hex mesh. I have managed to mesh it reasonably by webcutting a partial octagon from the center of the sphere, see pictures.

I wonder if there is a more efficient or built-in way to achieve a similar mesh using perhaps the sphere scheme? Is it possible to mesh an entire sphere and just split it down the middle?

Additionally, is there an optimal radius for the octagon given the radius of the sphere for a given target mesh size?

Cheers,
Anton

Hi @anton,

Would the polyhedron meshing scheme maybe be an option here?

So something like this:

create sphere radius 1 zpositive ypositive xpositive
volume 1 size 0.05
volume 1 scheme polyhedron
mesh volume 1

Have a nice day

Cheers,
Pat

polyhedron worked very well!

Thanks for the help!
