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 whole the wide range of simulation codes
that will be required for the success of the LWS
program

Example - Geospace Coupling
Global Magnetosphere
Inner Magnetosphere Ring Current
Ionosphere/Thermosphere

Geospace Codes
Global Magnetosphere-LFM
Ring Current-RCM

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, TICGM
• Communication channels via the InterComm package
  (http//www.cs.umd.edu/projects/hpsl/chaos/Researc
  hAreas/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 TICGM 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
