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.
