浸入式有限元法（IFEM）是一种解决流固耦合问题的先进数值方法。当它浸入流体中时，它可以通过适当的固体本构描述准确预测固体行为。在这里，我们介绍了原始 IFEM 和半隐式 IFEM 的概念和公式。半隐式形式是为了减轻当固体具有与流体显着不同的材料属性时的收敛性和时间步长约束。两个生物医学应用，分叉血管中的红细胞和人体声带振动，展示了算法的适用性和准确性。
The immersed finite‐element method (IFEM) is an advanced numerical approach that solves fluid‐structure interaction problems. It accurately predicts the solid behavior with a proper solid constitutive description when it is immersed in a fluid. Here, we present both the concepts and formulations of the original IFEM and semi‐implicit IFEM. The semi‐implicit form is to alleviate the convergence and time‐step constraint when the solid has material properties that are significantly different from the fluid. Two biomedical applications, red blood cell in bifurcated blood vessels and human vocal folds vibration, are presented to show the applicability and accuracy of the algorithms.
