run_dfdc_analysis#

run_dfdc_analysis(dfdc_object, print_output)[source]#

Executes the DFDC (Ducted Fan Design Code) executable with the specified input deck.

Parameters:

  • dfdc_object (DFDCAnalysis) –

    Analysis object containing the following attributes:
    • settingsData
      Configuration settings
      • new_regression_resultsbool

        Flag to use existing results instead of running analysis

      • filenamesData
        File path information
        • log_filenamestr

          Path to log file for stdout

        • err_filenamestr

          Path to error file for stderr

        • dfdc_bin_namestr

          Path to DFDC executable

        • casestr

          Case name for DFDC

    • current_statusData
      Current analysis state
      • deck_filestr

        Path to input deck file with DFDC commands

  • print_output (bool) – Flag to control whether DFDC console output is displayed

Returns:

exit_status – Return code from the DFDC process 0 indicates successful execution Non-zero values indicate errors

Return type:

int

Notes

This function handles the execution of the DFDC executable by:

  1. Purging any existing log and error files

  2. Opening the input deck file and feeding commands to DFDC

  3. Capturing and redirecting stdout/stderr to specified files

  4. Returning the process exit code

This function requires the third party DFDC executable to be installed. More information on the DFDC executable from Drela and Youngrencan be found at: https://web.mit.edu/drela/Public/web/dfdc/

If new_regression_results is True, the function will skip execution and return a success code (0) without running DFDC.
