Hey everyone,

I am modelling a solidification problem where we are tracking how inclusions move in a caster. They are represented by inert particles and I needed a way by which I can make a particle reach a wall/front as close as possible so that the distance between the particle and the wall is in nanometer scale. I am using*steady particle tracking and my distance comes out to be of order of 10^(-5)m. Even after changing the step length factor the distance comes out to be of the same order.

Try to decrease the tolerance in tracking parameters in DPM model (numerics if I remember well)
