From hemodynamics to engineering applications, many flow problems are
solved on networks. For feasibility reasons, computational domains are
often truncated and outflow conditions have to be prescribed at the end of
the domain under consideration.

We will show how to efficiently compute the impedance of specific networks
and how to use this information as outflow boundary condition. The method
is based on linearization arguments and Laplace transforms. The talk will
focus on hemodynamics applications but we will indicate how to generalize
the approach.

Joint work with Will Cousins (MIT) and Daniel Tartakovsky (UCSD)
