Hello,

I am new to Nektar++ and now working on vortex-induced vibration. The filter MovingBody can output the drag and lift forces acting on the body, however, I also require the moment data. I am modifying the MovingBody filter and now struck in the extraction of boundary points (used to calculate the moment). I wonder if there exists a method to extract edge points similar to GetEdgeNormal for extraction of edge normals. It will be greatly appreciated if you could give me some suggestions about this issue.

Thanks a lot.
Y. Wang
