Ursprungsversion vom 28/07/97 ! ! ! Description: ! ------------ ! This routine combines data of the PALM-subdomains into one file. In PALM ! every processor element opens its own file and writes 2D- or 3D-binary-data ! into it (different files are opened for xy-, xz-, yz-cross-sections and ! 3D-data). For plotting or analyzing these PE-data have to be collected and ! to be put into single files, which is done by this routine. ! Output format is NetCDF. Additionally, a data are output in a binary format ! readable by ISO2D-software (cross-sections) and by AVS (3D-data). !------------------------------------------------------------------------------! #if defined( __netcdf ) USE netcdf #endif IMPLICIT NONE ! !-- Local variables CHARACTER (LEN=2) :: modus, model_string CHARACTER (LEN=6) :: id_string CHARACTER (LEN=20) :: dimname, var_name CHARACTER (LEN=40) :: filename CHARACTER (LEN=2000), DIMENSION(0:1) :: var_list INTEGER, PARAMETER :: iwp = 4, spk = SELECTED_REAL_KIND( 6 ), wp = 8 INTEGER(iwp) :: av, danz, i, id, j, k, model, models, nc_stat, & nxa, nxag, nxe, nxeg, nya, nyag, nye, nyeg, & nza, nze, pos, time_step, & xa, xe, xxa, xxe, ya, ya_do, ya_tot, ye, ye_do, ye_tot, yya, yye, za, & ze, zza, zze #if defined( __lc ) || defined( __decalpha ) INTEGER(8) :: count, count_rate #elif defined( __nec ) INTEGER(iwp) :: count, count_rate #elif defined( __ibm ) INTEGER(8) :: IRTC #endif INTEGER(iwp), DIMENSION(0:1) :: current_level, current_var, & fanz, id_set, id_var_time, num_var INTEGER(iwp), DIMENSION(4) :: id_dims_loc INTEGER(iwp), DIMENSION(0:1,4) :: id_dims INTEGER(iwp), DIMENSION(0:1,1000) :: id_var, levels LOGICAL :: avs_output, compressed, found, iso2d_output, netcdf_output, & netcdf_parallel, netcdf_0, netcdf_1 REAL(wp) :: cpu_start_time, cpu_end_time, dx, simulated_time REAL(wp), DIMENSION(:), ALLOCATABLE :: eta, ho, hu REAL(wp), DIMENSION(:,:), ALLOCATABLE :: pf, pf_tmp REAL(spk), DIMENSION(:,:,:), ALLOCATABLE :: pf3d, pf3d_tmp PRINT*, '' PRINT*, '' PRINT*, '*** combine_plot_fields ***' ! !-- Find out if a coupled run has been carried out INQUIRE( FILE='COUPLING_PORT_OPENED', EXIST=found ) IF ( found ) THEN models = 2 PRINT*, ' coupled run' ELSE models = 1 PRINT*, ' uncoupled run' ENDIF ! !-- Find out if a precursor ocean run has been carried out INQUIRE( FILE='PRECURSOR_OCEAN', EXIST=found ) IF ( found ) THEN model_string = '_O' PRINT*, ' precursor ocean run' ELSE model_string = '' ENDIF ! !-- Do everything for each model DO model = 1, models ! !-- Set the model string used to identify the filenames IF ( models == 2 ) THEN PRINT*, '' PRINT*, '*** combine_plot_fields ***' IF ( model == 2 ) THEN model_string = '_O' PRINT*, ' now combining ocean data' PRINT*, ' ========================' ELSE PRINT*, ' now combining atmosphere data' PRINT*, ' =============================' ENDIF ENDIF ! !-- 2D-arrays for ISO2D !-- Main loop for the three different cross-sections, starting with !-- xy-section modus = 'XY' PRINT*, '' DO WHILE ( modus == 'XY' .OR. modus == 'XZ' .OR. modus == 'YZ' ) ! !-- Take current time #if defined( __lc ) || defined( __decalpha ) || defined( __nec ) CALL SYSTEM_CLOCK( count, count_rate ) cpu_start_time = REAL( count ) / REAL( count_rate ) #elif defined( __ibm ) cpu_start_time = IRTC( ) * 1E-9 #else PRINT*, '+++ INFORMATIVE: no time measurement defined on this host' #endif netcdf_parallel = .FALSE. ! !-- Check, if file from PE0 exists.
