WebThe output of the .find_peaks () function is an array that contains the indexes of each peak that has been identified. It can return also other information, in the case we had previously specified some options like “height” or “threshold” at the moment of the call. WebSep 2, 2024 · Hi @Katherine Zheng, this can happen when the contour data has coordinate points that are very close together, which when meshing forces the mesh to create extremely small elements.One method to help this is to remove one of the close together points, another is to refine the meshing parameters (i.e. smaller average size, larger …
