This multi-scale strategy allows for a dramatic reduction of the computational complexity and is suitable for "absorbing" outgoing pressure waves. In particular, it is of utmost interest for the description of blood motion in the arterial system.Fluid–structure interactionComputational fluid dynamicsAbsorbing boundary conditionsMulti-scale modelsHaemodynamicsOn the coupling of 3D and 1D Navier-Stokes equations for flow problems in compliant vesselstext::journal::journal article::research article
