Title:  TUMBLE a software package for the simulation of soft tissues in 
2D

Abstract:

As biology, as well as many other fields, requires computer
simulations of highly deformable materials, we have developed a 2D
moving-mesh package for the simulation of soft tissues.  We have
started with the simulation of red blood cells in a fluid flow where
the cells as well as the containing vessel, such as a heart, may be
highly deformable and have interesting dynamics.  We have chosen the
Lagrangian approach, that is, we move the mesh with the material. This
method over say Eulerian has the advantage that the systems to be
solved at each time frame, for say Navier-Stokes with immerse
membrane, are all linear.  In addition, there are many other
advantages that we will discuss in the talk. The main downside,
though, is that the meshing problems become much more difficult.  We
show how to address these meshing problems, as well as show some
interesting simulations.

This represents joint work with David E. Cardoze, Mark Olah, and Todd 
Phillips.
