Numerical treatment of boundary conditions to replace lateral branches in hemodynamics
International Journal For Numerical Methods In Biomedical EngineeringPeer ReviewedPorpora A. +32012Journals
SUMMARY In this paper, we discuss a technique for weakly enforcing flow rate conditions in computational hemodynamics. In particular, we study the effectiveness of cutting lateral branches from the computational domain and replacing them with non‐perturbing boundary conditions to simplify the geometrical reconstruction and the numerical simulation. All these features are investigated both in the case of rigid and compliant walls. Several numerical results are presented to discuss the reliability of the proposed method.Copyright © 2012 John Wiley & Sons, Ltd.
