  • Update on Working Model Users

    Many thanks to those who replied to my request for those interested in
    sharing their knowledge and experience with Working Model. The following
    are replies I have received so far. I will follow up on the suggestions
    made and then get back to the individuals listed and any others who would
    like to communicate on Working Model 2D and 3D.

    Original Message: We are currently working on competitive diving
    simulations using Working
    Model 2D by Knowledge Revolution. When I inquired about possible user
    groups for this software, KR was not aware of any. We are wondering if
    there are Working Model users on Biomch-L who might be interested in
    communicating with one another with respect to their experience with this
    software and particularly with the scripting feature.

    We are interested indeed. would you like to start a mailing list?

    From: Ton van den Bogert
    It might be good to browse the database of the ISB Technical Group Computer
    Simulation. There are about 100 members in this group. I have not heard of
    anyone using Working Model 2D, but there is a lot
    of technical expertise in this group. If you join the group, you can
    initiate a technical discussion on the TGCS-L mailing list.

    I am using WM3D and would be interested in a user group in biomechanics.

    I am currently using working model 2D, then 3D to develop a model of the
    lower extremities of the spine to the level of the 4th lumbar
    vertebrae...the work has been slow, however, a colleage in engineering is
    somewhat familiar with the program. It seems the greatest problem so far is
    data entry of the large kinematic and kinetic files needed in biomechanical

    We are beginning studies to use WM 2d/3d to aid in the studies of gait
    analysis (with theVicon 370/VCM system). We also intended to use WM for us
    to make analyses of prostheses (knees). I hope we can share information
    about the use of this program.

    I would be very interested in participating in a special interest group of
    WorkingModel users. I have developed a few biomechanical models for
    WorkingModel 3D, including automation scripts in Visual Basic. Please let
    me know if I can do anything to help get a forum started.

    During this coming the XVIIth Congress of the ISB, on August 8-13, 1999,
    in Calgary, I will present (Sunday, August 8, at the University of
    Waterloo) the tutorial on "Application of Computer Simulation to the
    Teaching of Biomechanics". I will use during my presentation the
    simulation tools:Mathcad,Matlab, and Working Model. I think , that during
    this tutorial will be an excellent time to organize an E-Forum on the
    Biomch-L for who might be interested in communicating with one another with
    respect to their experience with this software.

    Have you asked the same question on the Sportscience listserver? I'm not
    sure whether you'll get a better response there.

    I have just begun using Working Model (and old version we've had kicking
    around the lab) to simulate falls. I have spent many frustrating hours
    trying to use the script feature, and ultimately ended up entering the body
    segment geometry, inertial parameters and initial conditions manually (for
    a 15 segment model!).
    Despite it's appeal, and some interesting results from my simulations so
    far, I've found it cumbersome and computationally slow for complex models
    (such as a 15 segment human body with muscles and soft tissue contraints).
    I've recently contacted a Knowledge Revolution sales rep to inquire about
    an upgrade and was shocked at the price. However, the program appears to
    have awsome potential and I would be very interested in communicating with
    others who use it; perhaps mastering the scripting feature would make it's
    use feasible.

    I have limited experience working with Working Model 2D. I have nothing to
    contribute at the moment, but would appreciate being included in any list
    you develop which shares info. I think, as you must, that the program has
    some real possibilities for Biomechanics. Thanks for trying to get
    something going.

    Yes, our company is starting to use WM and would like to find a group to
    discuss issues with.

    I was using working model to simulate some simple movements and motor
    control. To progrmm control I used Matlab and WM Scripts. The results were
    encouraging for the relatively simple dynamics. Unfortunately during last
    year I was quite busy with the other projects and left WM for a while. If
    you want I could be more specific in terms of what has been done and what
    the problems I faced.

    I did some simulation work in my thesis and am now working in Bob Full's
    lab at UC Berkeley. I have used Working Model 2D and 3D and find that there
    are a lot of people here in the Biology Department that use it also (Rodger
    Kram, Claire Farley, etc) to model legged locomotion and other things. I am
    not very familiar with the scripting features, since I find it much easier
    to interface with MATLAB. But other people here are familiar with them.

    I'm a mechanical engineering prof and have used WM in a design course. I
    haven't yet applied it to biomechanics, but I'll be teaching a biomechanics
    course next year and may well use it, especially if I know of some others
    who have used it with whom I can exchange information. Please let me know
    what response you get.

    I would be interested in such a group, although my experience is more with
    Autolev and Animake. Autolev is based on Kane equations (analog to Lagrange
    equations) I have work on many models, some of which would be closed to
    your diving problem.(squat jump, ski jump in 2d)

    I am about to start using a suite of CAD and CAM software which will
    include Working Model, in my role as clinical engineer in the medical
    workshops of a large teaching hospital. As I am also the clinical engineer
    in two local gait laboratories, I can see potential overlap in the use of
    the software, and would be very interested in a user group.
