A Boundary Treatment Method For Simulating Fluid In Porous Media

We propose a novel fluid-boundary interaction
model based on SPH method which applys to the simulation
of fluid in the medium of complex boundary such as the porous
medium. High computational cost deficiency exists in previous
boundary treatment methods. This issue is particularly obvious
due to the complexity of boundary, and could lead to a significant
decline in simulation performance. Our approach treats the
boundary as triangular meshes, then models the interaction
between fluid particles and triangular meshes based on the elastic
collision model, which shows some advantages that traditional
methods do not have such as simplicity and high-efficiency. We
also design a fast neighbor boundary search method. Experiments
demonstrate that our method can handle the interaction between
fluid and boundary in complex scenario stably and efficiently.
