RESBAL CODE FACT SHEET
1. Code Name: RESBAL
2. Category: VIIb. Linear Stability: 2D Resistive
3. Responsible Physicist: M. S. Chance
4. Others involved in code development: A. H. Glasser, J. M. Greene
5. One line description: Fully compressible 4th order ODE solver for the MHD resistive ballooning equation.
6. Computer systems which code runs on: Cray
7. Typical running time:
8. Approximate number of code lines: 2000
9. Does this code read data files from another code? MAPDSK, MPOUT1 from mapping code.
10. Does this code produce data files that can be read by another code? No.
11. 1-2 paragraph description of code: Solves the fourth order fully compressible equations for the resistive ballooning equations using a shooting method. The eigenfrequencies are complex and the code is constructed to be interactively run in searching among the plethora of roads in the complex plane.
12. Similar codes to this code, and distinguishing differences: Kai and Grassie from Garching have a similar code but which uses finite elements instead. Culham's code is very similar to RESBAL.
13. Journal References describing code (up to 3): M. S. Chance, et al., Proceedings of the Seventh International Conference on Plasma Physics and Controlled Nuclear Fusion Research (IAEA, Vienna, 1979) Vol. 1, p. 677-687.
16. Present and recent applications of code: Not used recently.
17. Status of code input/output documentation. Check one: (X) does not exist ( ) incomplete ( ) exists
18. Year Code was first used and present frequency of use: Mid 70's.
Now,not used much because of lack of manpower.
19. Estimate of Man-Years invested in developing code: 0.5 yr.
20. Catagories of usage of Code (Check all that apply): (X) application code to do analysis and prediction of experiments (X) numerical testbed of theoretical ideas ( ) physics module to be used in integrated moddelling ( ) code for machine design
21. Language code is writen in: Fortran.
22. Results of intercomparisons with other codes and results of validation against experiments. Was the first and only such code. Difficult to compare with experiment.
