Extracting Pressure Data on a Spherical Surface Rotor in Hover Example

[NullNoyan]

Dear FLOWUnsteady Community,

Greetings! I hope you’re doing well. I’m reaching out to kindly ask for assistance from those experienced with the FLOWUnsteady package, as I’m working on the "rotor in hover" example and struggling with a specific task.

I need to extract pressure data at a spherical surface with a radius of, for example, 1 meter from the rotor. For each time step, I’d like to generate a table where the first few columns (e.g., x, y, z coordinates) represent points on this 1-meter radius spherical surface, and the next column contains the corresponding pressure values. However, I’m finding it difficult to set up the observer grid and extract the pressure data from the sphere’s surface in this format.

I’m unsure how to properly configure the spherical observer grid in the "rotor in hover" example to achieve this, or even if this task is feasible with FLOWUnsteady. Could anyone confirm if this is possible? If so, I’d greatly appreciate any guidance, code snippets, or references to relevant documentation to help me implement this correctly.

Thank you so much for your time and expertise. Your support would mean a lot, and I look forward to learning from the community.

Best regards.
