I'm using a 2D axisymmetric transient model. It is a two-phase model, where the primary phase is air and the secondary phase is discrete particles modelled using DPM. During the simulation, when the particle hits the axis it bounces back from it. So, to understand the particles' position I plotted the particle position graph via 'Particle track' under the result section. I plotted two graphs; 'Particle Y position' and 'Particle Radial position'. For the 'Particle Radial position' plot, the particle bounces back from the axis and continues its trajectory. But for 'Particle Y position', the particle seems to cut through the axis without bouncing(reflecting).
Since I'm using an axisymmetric model is it possible for the particle to cross through the axis? If so, what co-ordinates DPM utilizes even though the model is axisymmetric?
Thanks.June 24, 2021 at 9:52 amRobAnsys EmployeeCan you post the results?
