However, current solutions in the visual effects industry still largely rely on single-phase solvers and non-physical \u201cwhite-water\u201d heuristics. To address these limitations, we present Phase-Field-FLIP (PF-FLIP), a hybrid Eulerian\/Lagrangian method for the fully physics-based simulation of very large-scale, highly turbulent multiphase flows at high Reynolds numbers and high fluid density contrasts. PF-FLIP transports mass and momentum in a consistent, non-dissipative manner and, unlike most existing multiphase approaches, does not require a surface reconstruction step. Furthermore, we employ spatial adaptivity across all critical components of the simulation algorithm, including the pressure Poisson solver. We augment PF-FLIP with a dual multiresolution scheme that couples an efficient treeless adaptive grid with adaptive particles, along with a fast adaptive Poisson solver tailored for high-density-contrast multiphase flows. Our method enables the simulation of two-phase flow scenarios with a level of physical realism and detail previously unattainable in graphics, supporting billions of particles and adaptive 3D resolutions with thousands of grid cells per dimension on a single workstation.<\/p>\n<p><a href=\"https:\/\/ge.in.tum.de\/publications\/very-large-scale-two-phase-flip\/\">Adaptive Phase-Field-FLIP for Very Large Scale Two-Phase Fluid Simulation<\/a><\/p>\n<\/p><\/div>\n<div class=\"postinfo\">\n\t\t\t<span class=\"postmeta\">Posted by christopherbatty on <a href=\"https:\/\/www.physicsbasedanimation.com\/2025\/06\/03\/adaptive-phase-field-flip-for-very-large-scale-two-phase-fluid-simulation\/\">June 3rd, 2025<\/a> <\/span><br \/>\n\t\t\t\t\t\t<span class=\"postcats\">Posted in <a href=\"https:\/\/www.physicsbasedanimation.com\/category\/uncategorized\/\" rel=\"category tag\">Uncategorized<\/a><\/span><br \/>\n\t\t\t\t\t\t\t\t\t<span class=\"posttags\"\/>\n\t\t\t\t<\/div>\n<p>\t\t\t\t\t<!--\n\t\t\t\t<rdf:RDF xmlns:rdf=\"http:\/\/www.w3.org\/1999\/02\/22-rdf-syntax-ns#\"\n\t\t\txmlns:dc=\"http:\/\/purl.org\/dc\/elements\/1.1\/\"\n\t\t\txmlns:trackback=\"http:\/\/madskills.com\/public\/xml\/rss\/module\/trackback\/\">\n\t\t<rdf:Description rdf:about=\"https:\/\/www.physicsbasedanimation.com\/2025\/06\/03\/adaptive-phase-field-flip-for-very-large-scale-two-phase-fluid-simulation\/\"\n    dc:identifier=\"https:\/\/www.physicsbasedanimation.com\/2025\/06\/03\/adaptive-phase-field-flip-for-very-large-scale-two-phase-fluid-simulation\/\"\n    dc:title=\"Adaptive Phase-Field-FLIP for Very Large Scale Two-Phase Fluid Simulation\"\n    trackback:ping=\"https:\/\/www.physicsbasedanimation.com\/2025\/06\/03\/adaptive-phase-field-flip-for-very-large-scale-two-phase-fluid-simulation\/trackback\/\" \/>\n<\/rdf:RDF>\t\t\t-->\n\t\t<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Bernhard Braun, Jan Bender, Nils Thuerey Capturing the visually compelling features of large-scale water phenomena,such as the spray clouds of crashing waves, stormy seas, or waterfalls, involves simulating not only the water but also the motion of the air interacting with it.
