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

我们建议在2005年博尔德地幔对流研讨会成功的基础上，举办一次地幔和岩石圈动力学数值模拟研讨会。这次研讨会将比博尔德研讨会更广泛的受众，因为我们将把地幔对流和岩石圈动力学社区聚集在一起。我们希望讨论科学进展，更重要的是，与地幔岩石圈系统的起源和演化的定量建模有关的技术和科学问题。最近在集群计算、万亿级资源、软件支持和CIG代码共享方面的发展为科学进步带来了重大机遇，例如真正将岩石圈尺度变形模型与地幔对流计算相结合的前景。然而，一些当前的科学问题仍然没有得到解决，并了解这些动态的预测，定量意义上，是密切相关的计算问题，例如：我们如何能够有效地模拟热化学对流数值，在球形几何形状，充分处理夹带？我们如何在球面几何学中结合断层和移动板块边界，并研究区域性的俯冲系统演化？我们如何能准确地将应变局部化和大的粘度变化，以及什么是适当的宏观描述亚尺度的过程？研讨会将于2008年7月9日至11日在加州大学举行，为期三天。戴维斯讲习班召集人共同努力，提出了一个多样化和富有启发性的发言者小组和专题。会议形式包括一系列主题演讲和研讨会风格的演讲，有足够的空间观看海报和结构化，以及非结构化的讨论。这次研讨会将有几个更广泛的影响，超越了在地幔和岩石圈动力学社区推进数值模拟方法。首先，它将有助于培养研究生和研究人员在数值建模中使用的基本方法。每天下午的一个特别会议是专门用于教学的一些最重要的数值方法已经在使用或预计将举行地幔对流和岩石圈动力学社区的巨大潜力的基础。第二，研讨会将有助于加强新的和不断增长的社区在美国的岩石圈动力学建模。最后，讲习班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.
