Reply To: Sedimentation of one particle
assuming you are using version 1.5, there should be no general issues preventing you from investigating a single-sphere sedimentation setup. This has been done in 3D e.g. in [Trunk21](https://www.mdpi.com/2079-3197/9/2/11). As the terminal settling velocity results from an equilibrium between the respective forces acting on the particle, it can most likely not be achieved by “playing” with the parameters in a given domain, but requires a consistent parameter setup. It is worth noting at this point, however, that some setups will lead to large settling distances before hitting the terminal velocity. The default domain size of the dkt2d case will most likely not suffice in most cases and needs to be enlarged significantly.
