论文摘要
复杂的生物系统的模拟，例如对器官的血流描述，需要大量的计算能力以及对器官生理学的详细描述。我们提出了一种新型的最小二乘离散方法，用于使用肝组织的多孔培养基方法模拟肝小叶中正弦血流。不同最小二乘项的缩放术会导致鲁棒算法，并且固有的误差估计器提供了有效的改进策略。
The simulation of complex biological systems such as the description of blood flow in organs requires a lot of computational power as well as a detailed description of the organ physiology. We present a novel Least-Squares discretization method for the simulation of sinusoidal blood flow in liver lobules using a porous medium approach for the liver tissue. The scaling of the different Least-Squares terms leads to a robust algorithm and the inherent error estimator provides an efficient refinement strategy.
