OR are there significant changes to these codes that are needed to</div><div>accomplish the science you want to be doing? Should these changes be made or should resources</div><div>be focused on completely new codes?</div><div><br></div><div>What major development directions are in the works and how are these related to CIG?</div><div><br></div><div>The NSF proposal for the continuation of CIG: </div><div><br></div><div><a href="http://www.geodynamics.org/cig/proposalsndocs/documents/cig2-2009-proposal.pdf">http://www.geodynamics.org/cig/proposalsndocs/documents/cig2-2009-proposal.pdf</a></div><div><br></div><div>highlighted things like developing AMR codes (like Rhea), multiphysics coupling (solid and fluids</div><div>for mantle-lithosphere-magma simulations), adjoints and inversions and building on</div><div>existing packages like deal.II and FEniCS. What is the time-line for development of this new</div><div>generation of codes?</div><div><br></div><div>In short - what are your computational needs - are there CIG tools available now that could</div><div>be improved to meet these needs? If not, what capabilities should be the priorities in developing</div><div>new software?</div><div><br></div><div>Please e-mail us your feedback by next Tuesday, July 20th.</div><div><br></div><div>Sincerely,</div><div><br></div><div>Magali Billen and Wolfgang Bangerth</div><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Grande'; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Grande'; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Grande'; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div>-----------------------------</div><div>Associate Professor, U.C.
