Dear Lammps users,
I am trying to simulate fluid flow in complex porous medium using MDPD.
In this stage, I could built the solid wall model containing fluids as shown in the figure.
However, with respect to the solid wall boundary condition, I am not sure which options would be valid for my model for the boundary condition which fluid particles cannot penetrates inside solid wall of the complex porous medium.
I have tried ‘fix wall/reflect’ for cylindrical model but I did not work effectively and even this model has non-uniform pore structure, making harder to set the appropriate boundary condition.
Thus, please give me your advice how to set the reflecting boundary condition for my research.
Thanks
