“…The results obtained in this paper are a proof of concept, since they have been restricted to two space dimensions. Our preliminary results in [11,15] seems to show that the conclusion of this paper carry on with true three dimensional space unsteady simulation and complex geometry such as the carotid bifurcation in the neck. However realistic blood flow simulation requires more attention to inlet/outlet boundary condition and uncertainty assessment than we had in this paper.…”

“…For the non-homogeneous mixed boundary conditions a preprocessing step is added which consists of solving the zero mode equation with appropriate boundary conditions: (11) This method is easily generalized for an arbitrary number of subdomain and the matrix of the linear system corresponding to (10) has a pentadiagonal structure [10].…”

“…A number of steady and unsteady, two dimensional as well as three dimensional problems have been benchmarked in [12,11,15] and compared for verification with a finite element simulation run with the commercial code ADINA. Figures 19 to 21 show an example of a simple artificial stenose steady calculation.…”

“…This paper is a proof of concept based on a two dimensional incompressible NS solver that provides close to real time simulation for arbitrary shaped geometry. Preliminary results for carotid bifurcation in three space dimensions are reported in [11]. This simulator is part of a global hemodynamic software suite that has a data base and web interface to make the system as easy and practical as possible for MDs [15].…”

The objective of this paper is to present a fast parallel incompressible Navier Stokes (NS) simulator that has enough versatility to apply to various endovascular situations with ease in medical image integration. Our long term goal is to bring NS simulation to surgeons as an additional routine image modality that can complement existing medical imaging channels. Given a medical image describing the geometry of an artery, we are able to simulate the blood flow through an artery close to clinical conditions. To achieve this goal, our interface relies on the combination of the L2 penalty method to deal with complex geometry for solving the NS equations. We present here a high performance portable domain decomposition solver based on a tuning of the fastest linear solver depending on the subdomain and the processor architecture. This paper provides a detailed proof of concept in the two dimensional case. The three dimensional results will be reported in a companion paper.
