[aspect-devel] 3 composition/instability drip

[John Naliboff]

Hi Payman,

Thanks for sending this over.  To further assist, can you point to a 
specific model setup/publication this is based on (if it is based on 
one?). Also, can you send over an image of your initial compositional field?

The solver is not happy about something and it might be easier to 
diagnose with a few images.  I should have time later today or tomorrow 
morning to take a close look.  Currently playing catchup after traveling.

Cheers,
John
