Fluid injection into dry sand

Submitted by Zheng Hu on Fri, 03/23/2018 - 18:21

Dear all,

I am now focusing on simulating the process of fluid injection into dry sand (DEM particles). As I know, for the fluid field, I have to determine some certain boundary conditions for all fixed fluid boundaries. However, if I want to simulate the infiltration process, such as water infiltrate into dry sand, is there any method that I simulate the gradual infiltration process of the sand sample? Could anyone please give me any clues? Thanks very much.

Best,
Zheng
