Besh mesh/partitioning tequniques for a sphere?

[Luke720]

Hello,

I am trying to create a quality mesh on a sphere and it is causing me some trouble. The only mesh I have been able to apply is a tetrahedral mesh. I would prefer to use hex elements but I cannot seem to partition the sphere adequately for it to allow me to do so.

So my question is, how does one partition a sphere so that it can be meshed with hex elements?

Any advice or techniques would be greatly appreciated.

Thanks!
