我们提出了移动欧拉-拉格朗日粒子 (MELP)，这是一种用于模拟薄膜和泡沫上不可压缩流体的新型无网格方法。 MELP采用双层粒子结构，以高稳定性和高效率联合模拟详细的剧烈流动和大表面变形。此外，我们设计了多MELP：一种促进多个MELP系统之间基于物理的相互作用的机制，以模拟具有非流形拓扑演化的气泡簇和泡沫。我们展示了我们的方法在各种具有挑战性的薄膜现象中的有效性，包括双气泡的瑞利-泰勒不稳定性、边缘表面张力引起的泡沫破碎、高原边界的恢复、牛顿黑膜以及气泡簇上的旋风分离器。
We present the Moving Eulerian-Lagrangian Particles (MELP), a novel mesh-free method for simulating incompressible fluid on thin films and foams. Employing a bi-layer particle structure, MELP jointly simulates detailed, vigorous flow and large surface deformation at high stability and efficiency. In addition, we design multi-MELP: a mechanism that facilitates the physically-based interaction between multiple MELP systems, to simulate bubble clusters and foams with non-manifold topological evolution. We showcase the efficacy of our method with a broad range of challenging thin film phenomena, including the Rayleigh-Taylor instability across double-bubbles, foam fragmentation with rim surface tension, recovery of the Plateau borders, Newton black films, as well as cyclones on bubble clusters.
