Similar manipulations on several numpy arrays
You can get the behavior you want using getattr and setattr, this should do the trick for your first example:

for attr in ('v0', 'v1', 'nl', 'nh', 'ul', 'uh', 'V1'):
    setattr(ResultSimulation, attr,
            getattr(ResultSimulation, attr)[::-1].copy)


It should be obvious how to modify the others to fit the same pattern.
