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.
