Pore Pressure Boundary Condition For Consolidation Example

[coarse-snow]

Thank you for sharing Geotaichi. I am learning using two phase engine to solve saturated questions. I notice an example of consolidation here. In the example, there is no setting of free drainage boundaries, and the pore pressure is directly updated and solved on the particles, but there set free drainage boundary treatment for pore pressure in some other papers. I am curious about how pore pressure spreads and dissipates without any special pore pressure treatments. For the Consolidation example, I uesd the B-Bar method, result is very abnorma, at the first timesetp, there is no particle in the background gird.

It due to different governing equations, you can refers to some literature to figure it out
