Context: Finite element method (FEM) is widely applied to manifold areas of computational fluid dynamics (CFD). FEM, however, may be limited in the presence of time-dependent fluid geometries. Dealing with large deformations requires particular procedures like remeshing that may increase computation time considerably and introduce additional inaccuracy into the solution. The so-called Lattice Boltzmann method (LBM) can provide accurate and stable simulations even with extremely deformable geometries.

背景：有限元法 (FEM) 广泛应用于计算流体动力学 (CFD) 的多个领域。然而，有限元法在存在随时间变化的流体几何形状时可能会受到限制。处理大变形需要重新划分网格等特定过程，这可能会大大增加计算时间并给解决方案带来额外的不准确性。即使对于变形极大的几何形状，所谓的格子玻尔兹曼方法（LBM）也可以提供准确且稳定的模拟。
