Accurate modeling of blood flow provides insights into arterial stent design, surgical planning, and analysis of stroke risk. Unfortunately, fully detailed modeling of the cardiovascular system is computationally impossible due to the enormous number of blood vessels in the body.  Instead, a common technique is to choose a small subset of arteries to model in detail while accounting for the "un-modeled" parts of the cardiovascular system through boundary conditions.  A popular tactic for deriving such a boundary condition is to analytically solve a simple blood flow model in an idealized self-similar tree of arteries.  This technique, termed the "structured tree" boundary condition, is computationally cheap but is not broadly applicable since it assumes temporal periodicity.  We have developed a generalized version of the structured tree condition that lacks this restriction and is applicable to general transient flow regimes.  We will discuss the derivation of this condition and its nontrivial numerical implementation.  Additionally, computational results and a comparison to the original structured tree condition for periodic problems will be provided.
