When I evaluate the constrained distortional mode on shapes (raw-generated or using template_path) which have multiple nodes/elements representing the profile corners, the number of distortional modes 'n_dist_modes' increases (following n_dist_modes = n_r*4-2), and the resulting curve and displaced shape show influence of combined local and distortional modes.
with multiple corner elements:
with n_r=1 (no corner elements)
If I had to guess, I'd say that the code is struggling to differentiate these corner nodes from "main nodes".
Not sure if that has any effect on physical behavior, but it does make it more difficult to locate the local minimum for distortional buckling.
