论文摘要
沉浸的边界方法允许在时间域模拟中描述简单的笛卡尔网格上的复杂对象。这里采用的惩罚技术是一种出于身体动机的Brinkman方法，该方法通过包括摩擦项和有效的数量来将对象作为多孔材料建模。我们研究方法如何模仿不同的声学边界条件。关于不同的声学设置，包括刚性壁和各种吸收式配置，已验证它。
Immersed boundary methods allow describing complex objects on simple Cartesian grids in time-domain simulations. The penalization technique employed here is a physically motivated Brinkman method that models objects as porous material by including a friction term and an effective volume. We investigate how the approach can mimic different acoustic boundary conditions. It is validated concerning different acoustic setups, including rigid walls and various absorber configurations.
