| Summary | 0001698: Particle cloud hangs when bouncing of horizontal wall | ||||
| Description | Simulation of particles, with gravity and rebound as wall interaction, halts when particles touch the horizontal wall (floor). Interaction with vertical walls occurs correctly. | ||||
| Steps To Reproduce | I attach a case that demonstrates the problem. | ||||

The velocity boundary condition is set to "type zeroGradient;" on your wall patches. This isn't correct. In regions of outflow the flow pushes the particle out, and the wall keeps it in, thousands of times per time-step. This makes the simulation stall. Change the wall boundary condition to "type fixedValue; value uniform (0 0 0);". If I do this the wall interaction happens fine. |
