Abstract | In this paper, we discuss a technique for weakly enforcing
ow rate
conditions in computational hemodynamics. In particular, we study the
eectiveness of cutting lateral branches from the computational domain
and replacing them with non perturbing boundary conditions, in order
to simplify the geometrical reconstruction and the numerical simulation.
All these features are investigated both in the case of a rigid and of a
compliant wall. Several numerical results are presented in order to discuss
the reliability of the proposed method. |
