How to produce the filed map
- use program "Possion Superfish" from LANL http://laacg1.lanl.gov/laacg/services/download_sf.phtml or local copy under /home/zwzhao/work_halla/solid/solid_solid/poisson/
- It's a windows program and need installation, it can run with wine in linux or winXP, but not win7
- see manuals for detailed help, especially for the postprocessor program SF7.EXE
- produce mesh by AUTOMESH.EXE with input from a ".am" file, output file will be ".T35" with only geometry and material
- then run POISSON.EXE with the ".T35" file which will be added with field.
- use WSFPLOT.EXE to view the ".T35" file
- then run SF7.EXE on the ".T35" file, do the field extrapolation for a line, arc or grid, the result is in a txt file "OUTSF7.TXT"
- a ".TBL" filed file may be produced also which can be directly viewed by TABLPLOT.EXE
Field map files
- The Babar magnet configuration and result files from Eugene at svn database_io/halla12/solid/field/babar_from_Eugene
(note: center of solenoid is at 600cm)
- the Babar magnet files created by Zhiwen at svn database_io/halla12/solid/field/babar
(note: based on Eugene's file but moved to the center of solenoid to origin)
