| − | * use program "Possion Superfish" from LANL http://laacg1.lanl.gov/laacg/services/download_sf.phtml or local copy [http://hallaweb.jlab.org/12GeV/SOLID/download/PoissonSuperfish_7.18.exe]
| |
| − | : 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
