We present the computation of Lagrangian-based flow characterization measures for time-dependent, deformable-wall, finite-element blood flow simulations. The algorithm is demonstrated in a fluid-structure interaction simulation of blood flow through a total cavopulmonary connection, and results are compared with a rigid-vessel simulation. Overall, strong similarity in Lagrangian measures of the flow between deformable and rigid-vessel models was observed.
