Synopsis

Pattern formation, such as in chemotactic cell (microglia)
aggregation, is an important phenomenon within Biology and Chemistry.
Moving finite element methods are designed for tracking moving shocks
and complex structures with a fixed number of nodes, making these methods
ideal for chemotaxis models where, for the appropriate parameters, cells
aggregate into sharp peaks. In my talk I will discuss the general idea
of the adaptive mesh technique called "String Gradient Weighted Moving
Finite Elements" and I will present results to several
systems of non-linear Partial Differential Equations. I will
conclude the talk by discussing a 2D model for aggregation of microglia
in two spatial dimensions solved numerically using the String Gradient
Weighted Moving Finite Element method.
