I am running an MPM simulation in which I am trying to get a particle in a pipe to block an extruded 'leak' section by becoming fixed over the leak position. The particle is drawn to the leak by the pressure differential created by the 0 Pa pressure at the leak outlet (with 100k Pa inside the pipe). See below of a particle in contact with the leak:<\/p>\n
