Hello,


I am looking to couple OpenFOAM with Dakota. I started with tutorials available in Wolf Dynamics. I have been working on the simple cavity gradient case. Here's the Dakota input file -


environment
tabular_data
tabular_data_file = 'table_out.dat'

method
conmin_frcg
max_iterations = 100
convergence_tolerance = 1e-4
max_function_evaluations = 20


variables
continuous_design = 1
cdv_initial_point -1.8
cdv_lower_bounds -2.0
cdv_upper_bounds 3.0
cdv_descriptor 'x1'

responses
num_objective_functions = 1
numerical_gradients

method_source dakota
interval_type forward

#fd_gradient_step_size = .000001
fd_gradient_step_size = 1.e-5

# to instead use analytic gradients returned by the simulator comment the
# preceding two lines and uncomment the following:
## analytic_gradients

no_hessians

sense 'max'


interface
fork
asynchronous
#evaluation_concurrency = 4
evaluation_concurrency = 1
analysis_driver = 'OF_D.sh'
parameters_file = 'params.in'
results_file = 'results.out'
work_directory directory_tag

copy_files = 'templatedir/*'


# uncomment to leave params.in and results.out files in work_dir subdirectories
named 'workdir' file_save directory_save


# when using conmin_frcg (above) with analytic_gradients (below),
# need to turn off the active set vector



When I run this file, I get the following error -

/params.in: line 1: 1: command not found
/params.in: line 2: -1.800000000000000e+00: command not found
/params.in: line 3: 1: command not found
/params.in: line 4: 1: command not found
/params.in: line 5: 1: command not found
/params.in: line 6: 1: command not found
/params.in: line 7: 0: command not found

/params.in: line 8: 1: command not found


When I add the aprepro command to the following statement in the input file,
# uncomment to leave params.in and results.out files in work_dir subdirectories
named 'workdir' file_save directory_save aprepro


Here's the error I get -

/params.in: line 9: syntax error: unexpected end of file


It seems like the issue is with the Dakota parameters file format. But I am not sure how to fix it. Thank you for any help you can provide!
