Hi everyone,

I’m working on visualizing the wake distribution around a propeller hub in STAR-CCM+, and I’d like to create a plot similar to the one shown below. The plot represents the wake distribution on the propeller plane, with the radial axis (r/R) normalized by the propeller radius and the angular axis (0∘ to 360∘) showing the circumferential angles.

I have two specific questions:

- How can I create such a plot in STAR-CCM+ where the wake distribution is shown in a radial (polar) format? Is there a direct way to combine scalar field data with radial and angular axes like this?

-How can I add custom axes (e.g., the radial axis on the left and the angular axis at the bottom) to my plot in STAR-CCM+? Are there any tools or annotations available for this purpose?

If you could provide step-by-step guidance or direct me to relevant resources, it would be greatly appreciated.

Thank you in advance for your help!

STAR-CCM+ does not natively support polar plots within its built-in tools, making external software essential for generating such visualizations. To achieve this, I recommend combining custom data extraction in STAR-CCM+ with visualization techniques in external tools like MATLAB, Python's Matplotlib, or Excel.

Begin by defining a plane section that intersects the propeller hub at the desired location to capture wake distribution data. Once the plane section is established, you can sample scalar field data—such as velocity or pressure—at points distributed radially and circumferentially across the plane.

Data extraction can be conducted using surface integral reports, point probes, or by defining a custom coordinate system centered at the hub to map radial and angular coordinates explicitly. After gathering the necessary data, export it in a compatible format, such as CSV, for further processing and visualization.

If you prefer to remain within STAR-CCM+, annotations can be utilized to manually add axis labels and markers for angular and radial positions. Custom coordinate systems and scalar display functions may also help create pseudo-polar visualizations, although these have certain limitations compared to dedicated plotting software.
