  1. Integrated Numerical Simulation of the Solar-Terrestrial Environment LWS Grant NAG5-12652 C. Goodrich, Principal Investigator Goal: To develop and test a general software framework that is capable of linking into a coherent wholethe wide range of simulation codes that will be required for the success of the LWS program

  4. Integrated Numerical Simulation of the Solar-Terrestrial Environment • We show here the geospace coupling of our project, which is the most complex • Three core codes which are strongly coupled together - LFM, RCM, TI*CGM • Communication channels via the InterComm package (http://www.cs.umd.edu/projects/hpsl/chaos/ResearchAreas/ic/) • Data interpolation and manipulation Coupling processes using the capabilities of the Overture package (http://www.llnl.gov/CASC/Overture/) • Current Status of project • Separate (two-way) coupling between the LFM and TING (one of the TI*CGM family) codes and the LFM and RCM codes using InterComm • Initial implementation of the Electrostatic Potential Coupler for LFM-TING (interpolation, grid rotation, …) in Overture • Initial design for extension EP Coupler to low latitude • Future Focus • Implement Inner Magnetosphere Coupler in Overture • Create InterComm linkage and Overture coupler for coronal and heliosphere codes • Test optimize combined InterComm/Overture framework • Develop and field test user documentation
