I simulate a particle in 2D micro canal that it should move in moving mesh method.
The particle is rigid and with udf i enter the inertia and mass in dynamic mesh zone.
I choose 6dof and smoothing and remeshing in dynamic mesh zone .
And i choose center gravity of the particle in the body.
In boundry condition i choose slip on particle and wall . But the particle cant move. What should i do?
