Hi,
Glad to have you back! The rsl file seems corrupt, so I wasn't able to view it, but I did check your namelist, and your time_step immediately pops out to me. It should be no more than 6xDX, so you are likely getting CFL errors. Try changing that to no more than 60 and see if that helps. If not, send your new namelist.input file, and try again to send all of your rsl.error.* files in a single *.TAR file. Thanks!
