Hello Chris, Well it is not importing known equations into Mathematica. It is to start from scratch! I realize that a lot more information is needed to specify the problem. My question was more general. If someone wrote some equations for some 3D rigid body dynamics, I would like to look at the notebook for a start. I look at it as a building blocks problem: start easy and small and then build it more complex. Then refine the equations and so on.

If it is the latter, much more information is required (such as the geometry, all necessary constitutive relations for material and fluid properties, equations to simulate flows near all the surfaces, etc) On 3/3/07, Robert Pigeon <robert.pigeon at videotron.ca> wrote: > Greetings, > Does any one worked out the rigid body equations (in 3D) in a notebook?
