In certain locations I want to apply a drag force to the flow. I implemented it with forced dynamics and by modifying the external field. (Which is, if i’m correct, very similar to how the fringe region works?) I guess I was just confused at first because as a beginner with (Open)LB I thought a certain descriptor is defined for all lattice points, so I had SmagorinskyLinearVelocityForcedBGKdynamics for the whole domain. Now I have defined my own descriptor with external field and applied it to those locations with a drag force.
