Hello,
I am performing some simple powder flowing simulations, and I am interested in seeing the migration of one or more particles through the flow, i.e. tracking it.
I tried defining a group using the following syntax :
region group_test block -0.02 0.02 0 0.02 0 0.04 units box
group group1 region group_test
dump dmp all custom 20002 post/movingMesh_*.liggghts id type type mass x y z ix iy iz vx vy vz fx fy fz omegax omegay omegaz radius diameter
dump dump1 group1 custom 20002 post/group1_*.liggghtss id type type mass x y z ix iy iz vx vy vz fx fy fz omegax omegay omegaz radius diameter
But no cells are accounted in the group I defined. (As it is stated in Paraview).
So what methods can be used to show the migration of some particles in the powder along with showing all the particles in the system, i.e. using different colors for example.
best wishes,
Nizar
