solve/animate/pulse/write command fails on Linux but works on Windows

### 🐞 Description of the bug

The TUI command `solve/animate/pulse/write` for saving pathline files works correctly on Windows but fails on Linux (Ubuntu 24.04) when executed through PyFluent. The exact command works fine when executed directly in the Fluent GUI on Linux.

**Error message on Linux:**
```solve/animate/pulse/w Error: invalid command Error Object: "pulse"```

Is this a known limitation with PyFluent on Linux?

### 📝 Steps to reproduce

1. Launch PyFluent session on Linux (Ubuntu 24.04)
2. Load a case file with pathlines configured
3. Execute the following command:
```python
solver_session.execute_tui(f'solve/animate/pulse/write {specific_result_filename} {frames_output_dir}')

**Expected behavior**: Command should execute successfully and save pathline image files (as it does on Windows)
**Actual behavior**: Command fails with "invalid command Error Object: pulse" error

### Alternative approaches attempted
I also tried using the native PyFluent TUI interface methods, but these also resulted in errors:

#### Method 1 - Direct TUI path
```solver_session.tui.solve.animate.pulse.write(specific_result_filename, frames_output_dir)```

#### Method 2 - Settings API
```solver_session.settings.results.graphics.pulse.write(object_name=specific_result_filename, file_name=frames_output_dir)```

Reproduce the failure on Ubuntu 24.04 using solver_session.execute_tui with solve/animate/pulse/write, then compare it with the direct TUI and settings API calls described in the issue. Check whether the same command succeeds in the Fluent GUI on Linux and Windows. Done means the PyFluent command saves the pathline image files successfully on Linux or the limitation is documented.
