    Dear Dave,
    Yes, you are right. Since we are starting the studies here, it is to
    early to talk about harmonics and border effects, but he is doing a
    doctoral degree and he certainly will be following the path to the
    effects of non-linearities in the LIM's. Certainly the big question
    here, and I would be glad to hear your oppinion as an expert in the
    field, is: How could we simulate the non linearities caused by
    speed in a 2D static simulation? This is something that could
    make a doctoral thesis worth to read? We are just starting and if
    you have ideas to share I always will be glad to hear them.

    With regards and thanks for your attention.

    Sincerely,
