Workshop for Advancing Numerical Modeling of Mantle Convection and Lithospheric Dynamics at U.C. Davis on July 9-11, 2008

在2005年博尔德地幔对流研讨会成功的基础上，我们提议举办一个关于地幔和岩石圈动力学数值模拟的研讨会。这次研讨会将比博尔德研讨会的听众更广泛，因为我们将把地幔对流和岩石圈动力学社区聚集在一起。我们希望讨论与定量模拟地幔-岩石圈系统的起源和演化有关的科学进展，尤其是技术和科学问题。最近在集群计算、太尺度资源以及CIG软件支持和代码共享方面的发展为科学进步带来了重大机遇，例如将岩石圈尺度变形模型与地幔对流计算真正结合起来的前景。然而，一些当前的科学问题仍未解决，从预测和定量的意义上理解这些动力学与计算问题密切相关，例如：我们如何有效地在球形几何中模拟热化学对流，并充分处理卷带？如何将断裂和活动板块边界纳入球面几何，研究区域真实的俯冲系统演化？我们如何准确地将应变局部化和大粘度变化结合起来，对亚尺度过程的适当宏观描述是什么？研讨会将于2008年7月9日至11日在加州大学戴维斯分校举行，为期三天。研讨会召集人共同努力，提出了一个多样化和刺激的演讲者和主题群体。会议形式包括一系列主题演讲和研讨会风格的演讲，有足够的空间来观看海报，以及结构化和非结构化的讨论。除了在地幔和岩石圈动力学群落中推进数值模拟方法之外，本次研讨会还将产生几个更广泛的影响。首先，它将有助于培养研究生和研究人员在数值模拟中使用的基本方法。每天下午有一节特别课专门用于教授一些已经在使用或预计在地幔对流和岩石圈动力学群落中具有巨大潜力的最重要的数值方法的基础知识。其次，该研讨会将有助于加强美国岩石圈动力学建模的新兴和不断增长的社区。最后，研讨会将促进地幔动力学和岩石圈动力学建模者之间的合作。

We are proposing to hold a workshop on Numerical Modeling of Mantle and Lithospheric Dynamics to build on the success of the 2005 Boulder workshop on Mantle Convection. This workshop will be broader in terms of audience than the Boulder workshop in that we will bring together both the mantle convection and lithospheric dynamics communities. We wish to discuss scientific advances and, importantly, technical and scientific issues related to the quantitative modeling of the origin and evolution of the mantle-lithosphere system. Recent developments in cluster computing, tera-scale resources, and software support and code-sharing efforts of the CIG have brought about major opportunities for scientific progress, such as the prospect of truly combining lithospheric-scale deformation models with mantle convection computations. However, several current science issues remain unresolved and understanding the dynamics of these in a predictive, quantitative sense, is intimately connected to computational issues, for example: How can we efficiently model thermo-chemical convection numerically, in spherical geometries, with adequate treatment of entrainment? How can we incorporate faulted and moving plate boundaries in spherical geometry, and study regionally realistic subduction system evolution? How can we accurately incorporate strain localization and large viscosity variations, and what are the appropriate macroscopic descriptions for sub-scale processes? The workshop will be held over three days on July 9-11, 2008 at U.C. Davis. The workshop conveners have worked together to propose a diverse and stimulating group of speakers and topics. The conference format includes a range of keynote and workshop style presentations, with ample room for poster viewing and structured, as well as unstructured, discussion. This workshop will have several broader impacts beyond advancing numerical modeling methods in the mantle and lithospheric dynamics communities. First, it will serve to train graduate students and researchers in fundamental methods used in numerical modeling. One special session each afternoon is reserved for the specific purpose of teaching the fundamentals of some of the most important numerical methods already in use or anticipated to hold great potential for the mantle convection and lithospheric dynamics communities. Second, the workshop will serve to strengthen the new and growing community of lithospheric-dynamics modelers in the US. Finally, the workshop will facilitate starting collaborations between mantle dynamics and lithospheric dynamics modelers.
