Cart3D PySAGAS Wrapper

The PySAGAS wrapper for Cart3D includes a main wrapper module and a utilities module.

class pysagas.sensitivity.cart3d.cart3d.Cart3DSensitivityCalculator[source]

PySAGAS Cart3D flow sensitivity calculator.

__init__(freestream, sensitivity_filepath, components_filepath=None, pointdata=None, celldata=None, write_data=False, verbosity=1, **kwargs)[source]

A PySAGAS sensitivity calculator for Cart3D.

Parameters:

  • freestream (FlowState) – The flow state of the freestream.

  • sensitivity_filepath (str) – The filepath to the geometry sensitivities.

  • components_filepath (str, optional) – The filepath to the Components.i.plt file to be processed. The default is None.

  • pointdata (pd.DataFrame, optional) – The point data. Must be supplied with celldata.

  • celldata (pd.DataFrame, optional) – The cell data. Must be supplied with pointdata.

  • write_data (bool, optional) – Write the flow data to CSV files. The default is True.

  • verbosity (int, optional) – The verbosity of the code. The defualt is 1.

Return type:

None

_transcribe_cells(parameters)[source]

Transcribes the cells from Components.i.plt files into PySAGAS Cell objects.

Parameters:

parameters (List[str]) – A list of the geometric design parameters.

Returns:

cells – A list of all transcribed cells.

Return type:

List[Cell]

pysagas.sensitivity.cart3d.utilities.process_components_file(a_inf, rho_inf, filepath='Components.i.plt', write_data=True, verbosity=1)[source]

A ParaView script to process Components.i.plt to extract points and cells with data attached.

Parameters:

  • a_inf (float) – The freestream speed of sound (m/s).

  • rho_inf (float) – The freestream density (kg/m^3).

  • filepath (str, optional) – The filepath to the Components.i.plt file to be processed. The default is Components.i.plt.

  • write_data (bool, optional) – Write the flow data to CSV files. The default is True.

  • verbosity (int, optional) – The verbosity of the code. The defualt is 1.

Returns:

  • points (pd.DataFrame) – A DataFrame of the point data.

  • cells (pd.DataFrame) – A DataFrame of the cell data.

Return type:

Tuple[DataFrame, DataFrame]
