meshConversion.classify_surfaces(h5_file_path)[source]

Classifies and identifies the surfaces (top, bottom, internal, and external) of a mesh structure based on node information from an HDF5 file.

Args:

h5_file_path (str): The file path to the HDF5 file containing mesh data.

Functionality:

  • Reads the mesh data from the HDF5 file, including node coordinates and element information.

  • Groups mesh elements by ID.

  • Identifies the top and bottom surfaces based on the z-coordinate of the nodes.

  • Calculates the radius of each remaining surface and classifies them as internal or external.

  • Saves the surface classification in a JSON file.

Returns:

None

meshConversion.estimate_radius_by_sections(points, num_sections=50)[source]

Extracts and returns the node coordinates of the current face of the mesh element.

Args:

key (int): The identifier key for the group of mesh elements. grouped_elements (dict): Dictionary where keys are element IDs and values are arrays of grouped mesh elements. nodes (ndarray): Array containing the coordinates of the mesh nodes.

Returns:
ndarray: The node coordinates corresponding to the extracted face,

after removing duplicates and shifting positions by 1.

meshConversion.extract_current_face_nodes(key, grouped_elements, nodes)[source]

Extracts and returns the node coordinates of the current face of the mesh element.

Args:

key (int): The identifier key for the group of mesh elements. grouped_elements (dict): Dictionary where keys are element IDs and values are arrays of grouped mesh elements. nodes (ndarray): Array containing the coordinates of the mesh nodes.

Returns:
ndarray: The node coordinates corresponding to the extracted face,

after removing duplicates and shifting positions by 1.

meshConversion.main(argv)[source]

Main function to process a mesh file and export its properties.

Args:
argv (list): List of command-line arguments.

  • If no arguments are provided, a file dialog is opened to select the mesh file.

  • If one argument is provided, it is treated as the path to the mesh file.

  • If two arguments are provided, the first is the path to the mesh file, and the second is the export path.

Functionality:

  • Reads a mesh file in either UTF-8 or ISO-8859-1 encoding.

  • Calls helper functions to find mesh delimiters and write mesh information to a specified export path.

  • If no file path is provided via the command-line arguments, a file selection dialog is opened.

Raises:

SystemExit: Exits the program if more than two arguments are provided.
