About half the time I can get rid of segfaults by increasing TIME_STEP_SOUND in run_timestep.conf from it's default of 4. I've gone as high as 16, and that seems to help, although it slows the simulation substantially to go above 8. Sometimes choosing different microphysics or cloud physics helps also, as well as *slightly* increasing the grid spacing. However, I have not yet been able to run a simulation below ~1.5 km resolution without a segfault (I have tried the same simulation on three different computers!).
I think it would be great if others can share their experiences with this problem on this "Sharing Knowhow" forum! One idea might be substituting the executables from WRF 3.4 into EMS. (I don't know if later versions of WRF are more stable or not.)
Tell us your magic!!!!
