Comments:

Same problems as 2401; the system is overdriven. Need lower power. Getting the lh spike again. This is the beginning of a lot of runs with these parameters. Need to use NZONES=100 and NJSMLH=0. fbs max=79%, but requires jqlim. Again I need to fix this up and the result should be nice. Not enough radial resolution. Try with about 2.3MW LH power. For more information about the run see the input namelist.
