[CIG-LONG] cig-long email list

[Garrett Ito]

Hi Mark,

  Good-- I'm glad to see 3D is starting to get a footing in the community.  This is my main reason for using Gale as I already do faulting in 2D with FLAC (and it is my understanding that SNAC is too computationally expensive in 3D ?).  Correction... Mohr-Coulomb has been removed from Gale because it was unstable in 3D and is identical to Drucker-Prager in 2D.
