📝 Description of the Feature

In this article, we will explore the implementation of a new feature in the save_mesh function, which will enable users to connect to the pyfluent turbo workflow. The addition of a prefix argument will allow users to customize the naming of their mesh files, ensuring that each gtm has a unique cell name and boundary conditions name, as well as rotor and stator mesh names.

The current implementation of the save_mesh function is as follows:

def save_mesh(self, filename: str, onefile: str, onedomain: str) -> None:
    """
    Save generated mesh to a file.

    :param filename: Name of the mesh file to save.
    :type filename: str
    :param onefile: If enabled (true), write all of the available meshes to a single mesh file. The default is ``true``.
    :type onefile: str
    :param onedomain: If enabled (true), combine any inlet and outlet domain meshes with the passage domain,
        to form a single assembly. The default is ``true``.
    :type onedomain: str
    """
    ...

However, this implementation has a limitation, as it does not allow users to customize the naming of their mesh files. This can lead to confusion and errors when working with multiple mesh files.

💡 Steps for Implementing the Feature

To implement the prefix argument in the save_mesh function, we need to follow these steps:

Step 1: Add the prefix Argument

We need to add a new argument to the save_mesh function, which will be used to specify the prefix for the mesh file names. This argument will be optional, and its default value will be an empty string.

def save_mesh(self, filename: str, onefile: str, onedomain: str, prefix: str = '') -> None:
    """
    Save generated mesh to a file.

    :param filename: Name of the mesh file to save.
    :type filename: str
    :param onefile: If enabled (true), write all of the available meshes to a single mesh file. The default is ``true``.
    :type onefile: str
    :param onedomain: If enabled (true), combine any inlet and outlet domain meshes with the passage domain,
        to form a single assembly. The default is ``true``.
    :type onedomain: str
    :param prefix: Prefix for the mesh file names. Default is an empty string.
    :type prefix: str
    """
    ...

Step 2: Update the Mesh File Naming

We need to update the mesh file naming to include the prefix specified by the user. We can do this by using the prefix argument to construct the file name.

# Get the file name without the extension
file_name_without_extension = os.path.splitext(filename)[0]

# Construct the file name with the prefix
file_name_with_prefix = f"{prefix}_{file_name_without_extension}.vtk"

Step 3: Save the Mesh File

We need to save the mesh file with the updated file name.

python

self.save_mesh_file(file_name_with_prefix)

### 💻 Example Use Case

Here is an example use case for the `save_mesh` function with the `prefix` argument:

```python
# Create an instance of the mesh saver
mesh_saver = MeshSaver()

# Save the mesh file with a prefix
mesh_saver.save_mesh("mesh_file.vtk", "true", "true", "my_mesh")

In this example, the save_mesh function is called with the prefix argument set to "my_mesh". This will result in the mesh file being saved with the name "my_mesh_mesh_file.vtk".

📊 Benefits of the Feature

The addition of the prefix argument to the save_mesh function provides several benefits, including:

  • Customizable mesh file naming: Users can now customize the naming of their mesh files by specifying a prefix.
  • Improved organization: Users can now organize their mesh files in a more structured way by using a prefix to identify related files.
  • Reduced errors: Users are less likely to make errors when working with multiple mesh files, as the prefix provides a clear indication of the file's purpose.

🤔 Frequently Asked Questions

In this article, we will answer some frequently asked questions about implementing the prefix argument in the save_mesh function.

💬 Q1: Why do I need to add a prefix argument to the save_mesh function?

A1: The prefix argument is needed to provide a customizable way to name mesh files. Without it, all mesh files would have the same name, which can lead to confusion and errors when working with multiple mesh files.

💬 Q2: How do I add the prefix argument to the save_mesh function?

A2: To add the prefix argument, you need to modify the save_mesh function to accept an additional argument, which will be used to specify the prefix for the mesh file names. The default value of this argument should be an empty string.

def save_mesh(self, filename: str, onefile: str, onedomain: str, prefix: str = '') -> None:
    ...

💬 Q3: How do I use the prefix argument to customize the mesh file naming?

A3: To use the prefix argument, you need to specify a value for it when calling the save_mesh function. This value will be used to construct the file name of the mesh file.

mesh_saver.save_mesh("mesh_file.vtk", "true", "true", "my_mesh")

In this example, the prefix argument is set to "my_mesh", which will result in the mesh file being saved with the name "my_mesh_mesh_file.vtk".

💬 Q4: What are the benefits of using the prefix argument?

A4: The benefits of using the prefix argument include:

  • Customizable mesh file naming: Users can now customize the naming of their mesh files by specifying a prefix.
  • Improved organization: Users can now organize their mesh files in a more structured way by using a prefix to identify related files.
  • Reduced errors: Users are less likely to make errors when working with multiple mesh files, as the prefix provides a clear indication of the file's purpose.

💬 Q5: How do I handle cases where the prefix argument is not provided?

A5: If the prefix argument is not provided, you can use the default value of an empty string. This will result in the mesh file being saved with a default name.

mesh_saver.save_mesh("mesh_file.vtk", "true", "true")

In this example, the prefix argument is not provided, so the mesh file will be saved with the default name "mesh_file.vtk".

💬 Q6: Can I use the prefix argument with other mesh file formats?

A6: Yes, you can use the prefix argument with other mesh file formats, such as STL or OBJ. However, you will need to modify the save_mesh function to handle the specific file format.

💬 Q7: How do I troubleshoot issues with the prefix argument?

A7: If you encounter issues with the prefix argument, you can try the following:

  • Check the documentation: sure you have read and understood the documentation for the save_mesh function and the prefix argument.
  • Verify the argument value: Check that the value of the prefix argument is correct and matches the expected format.
  • Test the function: Test the save_mesh function with different values of the prefix argument to ensure it is working correctly.

By following these steps and troubleshooting tips, you should be able to successfully implement the prefix argument in the save_mesh function and customize the mesh file naming to suit your needs.
