Hi David,

Is your post in the right thread?  I can't see sharp features
in your spheres.

Can you provide the data set of the sphere, and the call
to the mesh generator (plus the #includes and typedefs)
so that we can try to reproduce and fix it.

The same for a multidomain segmented image.

best,

andreas
