Hi, I am currently doing a simulation on an 2D elliptical airfoil with a hummingbird motion. I realized that when I plot out my Cl and Cd graphs, I see lots of spikes in the graph.
May I know what could be the problem and how do I eliminate these spikes? Any help is greatly appreciated! What I am trying to do is something like this video: https://www.youtube.com/watch?v=01hOD68DxrM *the video is not by me |

Hi, does anyone know how? I suspect it could be due to remeshing since I am using a mixed mesh(quad+triangles).
I have tried reducing the timestep to 0.00005 and yet I am still seeing lots of spikes. Thanks in advance! |
