Home / Products / Audio or Video Computer Animation of a Fluid-filled Deformable Tube In the Spring 2005 semester, students taking ME 322-Computer Methods in Engineering were assigned a problem involving the unsteady flow of an incompressible fluid in a collapsible tube. Its solution required implementation of a number of numerical techniques taught in the course, including the numerical solution of a system of non-linear, coupled partial differential equations by an implicit finite differencing scheme, the solution of sparse systems of linear algebraic equations, and curve fitting of material properties from experimental data. The class was divided into five groups, with four or five students per group, and each group was required to write a subprogram to perform a subtask of the problem. The final product was a computer animation showing the deformation of the tube and the local fluid velocity distribution.
