Therefore, it might be worth trying to improve its runtime.\\n\\nThe vast majority of mono_flux_limiter's runtime is computing mean_w_up and mean_w_down.  \\n\\nI can't recall: Why didn't l_constant_thickness work?  Which case failed?  Is this worth revisiting with the most recent version of CLUBB?\\n\\nIf l_constant_thickness doesn't work, could we try to approximate the exact formulas for mean_w_up and mean_w_down?  E.g., could we try something simple such as\\n\\nmean_w_up = max( 0, wm + sqrt(wp2) ) ,\\n\\nmean_w_down = min( 0, wm - sqrt(wp2) ) ?\\n\\nPerhaps this is too simple, but it seems like it ought to be possible to construct a simple formula that depends on wm, wp2, and possibly wp3.\\n\\nAn alternative is to expand your exact expressions in either Taylor series or asymptotic expansions.\", \n    \"reporter\": \"vlarson@uwm.edu\", \n    \"cc\": \"\", \n    \"resolution\": \"wontfix\", \n    \"_ts\": \"1295374618000000\", \n    \"component\": \"clubb_src\", \n    \"summary\": \"Monotonic flux limiter: Improve runtime by approximation\", \n    \"priority\": \"minor\", \n    \"keywords\": \"\", \n    \"time\": \"2009-06-22T19:59:29\", \n    \"milestone\": \"Improve runtime of CLUBB\", \n    \"owner\": \"eihoppe@uwm.edu\", \n    \"type\": \"enhancement\"\n}\n```\n"}}
