Hello Foamers,

For my project, I need to calculate the radius of curvature of the streamlines.
I developed a solver and needed to include the radius of curvature of the streamlines.

Please help me calculate the radius of the curvature and how to implement it in the OpenFoam-10.

Thank You

You will need to go into the streamLineBase writeToFile() method. After all of the writing is over, you will have access to the allTracks_ point information (trimmed to any bounding box and with empty tracks removed). From there you can walk the segments and calculate the curvature.

Thank you very much Mark for your valuable reply,
is there any example or case which I can follow to include the streamLineBase method. Till now I didn't dig deeper in OF. Any other suggestions can also work.

I can also work with the geometrical curvature. Any insight how to calculate curvature using mesh data (coordinates) will be valuable for me.
i already posted a separate thread for the same (Geometrical Curvature).

You will have to dig into the code yourself, but I guess that is what your project is about...
