Fluid transport in and between porous materials

Physically-based realistic simulation of cloth and fluid are both important research areas in Computer Graphics. There is significant research of fluids interacting with porous materials in applied physics. However, only a few research studies have been conducted for the dynamics of liquid transportation between porous materials with wetting effects. [Huber, et al. 2014] presented a two-way coupling method between fluid and infinitesimally thin cloth. However, their approach cannot handle porous solids or oversaturated piece. [Patkar and Chaudhuri 2013] proposed a three-stage method to support liquid diffusion in volumetric objects. However, fluid transport between porous materials which is tightly close to each other was not considered.
