CSEM Experience with Community Modeling

Tamas Gombosi

What We Provide Today• SWMF source code is freely available (after registration)• SWMF has extensive documentation on-line

– 150 page User Manual– Publications describing the SWMF and BATS-R-US are online (in

PDF format)• User friendly web interface

– Code control, run control, visualization• Daily test run on at least five platforms

– CVS version control– E-mail notification of failures

• BATS-R-US was the first model at CCMC– We have 7 years of experience and good relations– Provide regular updates and help troubleshooting– ~60% of all CCMC runs were made with CSEM codes

Main Issues (Tamas’ Opinion)

• Who chooses the Community models?• What are the expectations

– Troubleshooting– Documentation– Validation

• Providing short test runs with all input and output files is essential

• Source code needs to be available (but with licence agreement)

• Honesty with model/physics limitations and problems

Model Issues

• From magnetogram to corona– Synoptic magnetic field– Plasma parameters– How to heat the corona?

• From corona to solar wind– How to match observations at the Sun and Earth?– We need to move to full qualitative models

(providing plasma and magnetic field parameters)

• STEREO images cannot be interpreted without qualitative 3D models

• Components of the framework can be easily selected for use.

• Some components have multiple versions or even alternative models

GUI:Run Control

• Upload SW driver or satellite position files.

• Edit run parameter files.• Edit queue submission

files.• Execute jobs.

GUI:Visualization

• Visualize run output using quality templates with many customizable options.

• Outputs postscript, png, animated gif, …
