Hi<br><br>I am running the wrf model for 2 domains and I'm using ndown for this purpose. However, I have a problem running ndown and I'm lost about the solution. I can generate correctly the input files to run the program, but after running ndown the following error appears in rsl.error file:<br> <br>-------------- FATAL CALLED ---------------<br> FATAL CALLED FROM FILE: <stdin> LINE: 355<br> program ndown: opening too many files<br> -------------------------------------------<br><br>The namelist.input file that I have been using is:<br><br>&time_control<br>run_days = 0,<br>run_hours = 12,<br>run_minutes = 0,<br>run_seconds = 0,<br>start_year = 2010, 2010,<br>start_month = 10, 10,<br>start_day = 15, 15,<br>start_hour = 00, 00,<br>end_year = 2010, 2010,<br>end_month = 10, 10,<br>end_day = 16, 16,<br>end_hour = 00, 00,<br>interval_seconds = 21600,<br>input_from_file = .true., .true.,<br>history_interval = 30, 30,<br>frames_per_outfile = 1000, 1000,<br>restart = .false.,<br>restart_interval = 720,<br>io_form_history = 2,<br>io_form_restart = 2,<br>io_form_input = 2,<br>io_form_boundary = 2,<br>io_form_auxinput2 = 2,<br>debug_level = 0,<br>/<br>&domains<br>time_step = 90,<br>time_step_fract_num = 0,<br>time_step_fract_den = 1,<br>max_dom = 2,<br>s_we = 1, 1,<br>e_we = 244, 292,<br>s_sn = 1, 1,<br>e_sn = 187, 235,<br>s_vert = 1, 1,<br>e_vert = 28, 28,<br>p_top_requested = 5000,<br>num_metgrid_levels = 27,<br>num_metgrid_levels = 27,<br>num_metgrid_soil_levels = 4,<br>dx = 2766.667, 922.222,<br>dy = 2766.667, 922.222,<br>grid_id = 1, 2,<br>parent_id = 1, 1,<br>i_parent_start = 1, 57,<br>j_parent_start = 1, 48,<br>parent_grid_ratio = 1, 3,<br>parent_time_step_ratio = 1, 3,<br>feedback = 0,<br>smooth_option = 0,<br>use_adaptive_time_step = .true.,<br>step_to_output_time = .true.,<br>target_cfl = 1.2,<br>max_step_increase_pct = 5,<br>starting_time_step = -1,<br>max_time_step = -1,<br>min_time_step = -1,<br>/<br>&physics<br>mp_physics = 3, 3,<br>ra_lw_physics = 1, 1,<br>ra_sw_physics = 1, 1,<br>radt = 30, 30,<br>sf_sfclay_physics = 1, 1,<br>sf_surface_physics = 2, 2,<br>bl_pbl_physics = 1, 1,<br>bldt = 0, 0,<br>cu_physics = 1, 1,<br>cudt = 5, 5,<br>isfflx = 1,<br>ifsnow = 0,<br>icloud = 1,<br>surface_input_source = 1,<br>num_soil_layers = 4,<br>sf_urban_physics = 0, 0,<br>maxiens = 1,<br>maxens = 3,<br>maxens2 = 3,<br>maxens3 = 16,<br>ensdim = 144,<br>tmn_update = 1,<br>sst_skin = 1,<br>/<br>&fdda<br>/<br>&dynamics<br>w_damping = 0,<br>diff_opt = 1,<br>km_opt = 4,<br>diff_6th_opt = 0, 0,<br>diff_6th_factor = 0.12, 0.12,<br>base_temp = 290.,<br>damp_opt = 0,<br>zdamp = 5000., 5000.,<br>dampcoef = 0.2, 0.2,<br>khdif = 0, 0,<br>kvdif = 0, 0,<br>non_hydrostatic = .true., .true.,<br>moist_adv_opt = 1, 1,<br>scalar_adv_opt = 1, 1,<br>/<br>&bdy_control<br>spec_bdy_width = 5,<br>spec_zone = 1,<br>relax_zone = 4,<br>spec_exp = 0.33,<br>specified = .true.,<br>nested = .false., .true.,<br>/<br>&grib2<br>/<br>&namelist_quilt<br>nio_tasks_per_group = 0,<br>nio_groups = 1,<br>/<br><br>I'm new using wrf model.
