ABSTRACT
Two tasks must be performed to obtain numerical simulations of human body motion: first, the governing equation must be developed and second, the equation must be solved. The form of the governing equations depends to the same extent upon the particular application of interest. The numerical solution of the equations is facilitated by expressing the governing differential equations in the first-order form. The chapter considers an outline of procedures for both the numerical development and the solution of the governing equations and employs details of the procedures depend upon the software. To develop a numerical methodology of human body dynamics which is applicable to a general class of problems, it is useful to start with a manybodied human body model whose limbs are constrained. The chapter outlines an algorithmic procedure for numerically generating and solving the governing equations. The computational efficiency is dependent upon two items: the efficiency of the simulation algorithm and the efficiency of the numerical integration.
