My talk will culminate in a model for chemical gradient detection by
migrating cells that change shape. I will first present a method for
solving reaction-advection-diffusion equations inside a deforming
region, with a moving boundary. The method employs a "distance map"
that is constructed by storing the shortest distance to the boundary at
each node on a grid. The gradient of the distance map provides a vector
that points from each node to the boundary, which is a known distance
away. These vectors and corresponding distances give exactly the
displacements that will move nodes onto the boundary, from points
nearby. This yields a structured, boundary-fitted grid that provides
the basis for a finite-volume method
