Hi everyone,
Upon starting my simulation the Cd listed is unbelievably high, as you can see it does begin to fall but it seems as though it would take an age to be what would be expected for the cylindrical case im running. I have run a previous simulation of a similar case where the geometry was simply 1/5 of the current size and this resulted in results that made sense. Does this fact mean there is an issue with my simulation or is this to be expected? I have attatched my, mesh and a screenshot of the solver for convenience. Many thanks in advance
