Hi, when trying to run examples, I get this error:

    154 boundary_face_idxs = []

ValueError: Invalid mesh indices, t has zero rows (t.shape = [0, 3]) 

Do I make something wrong?

thanks, Petr

Hi, It seems like the bone surface mesh models are not being read properly. When running the "hj_cartilage.ipynb" code, were you able to visualize the left femur and pelvic bones?
