I am working on developing a custom GUI within ParaView that directly links to OpenFOAM case files. Specifically, I would like to modify the velocity inlet values in the `0/U` file by entering a value in the ParaView interface and updating it with a button click. This action should automatically update the corresponding value in the `0/U` file without manually opening and editing the file.

I would like to know if there are any existing plugins or features in ParaView that align with this functionality.

I would appreciate any guidance or recommendations on how to achieve this.
