To model a complex arterial or venous network, the use of one-dimensional models (1D) allows to recover a global description of the pressure propagation with a reduced computational effort
The research focused on the numerical discretization of single 1D compartments with different schemes, such as the Taylor-Galerkin method, on the treatment of different mechanical properties, on the study of different vessel laws, on the extension to curve pipes, and on the treatment of bifurcations
The 1D modelling has been applied to different context, e.g. the simulation of the venous system of a human leg and the assisted Fontan procedure,
Arterial network characterized by 55 vessels
