Abstract: Based on an analysis of the relationship between the fluid and the cloth, a new simulation approach is presented for the water flowing through the cloth. We introduce a physical model based on the improved massspring model. Similar to the particle model, we use the porousparticles structure, and the pores are the fluid storage space. Due to the difference of the fluid storage between the neighboring particles, the generated capillary pressure drives the flowing among all particles. According to the Darcy’s law, our physical model can control the whole flowing process. According to the different saturation, we map different textures to demonstrate the variation of the wetting cloth materials. In this way, our model has high computational efficiency and strong extensibility.
