[aspect-devel] Question about spherical shell subset

[John Naliboff]

Hi Felipe,

If you would like to specify arbitrary opening angles in 3D, the two 
options are the "chunk" and "ellipsoidal_chunk" geometry models. There 
are a number of examples in the tests folder that show how to specify 
the opening angles.

Cheers,
John
