Hello, I am new to OpenLB and also to simulations using Lattice-Boltzmann method. I am trying to simulate the cylinder3d sample case for higher velocities/Reynolds numbers compared to the default value (V = 0.2 m/s, Re = 20). However, when I try to increase the Re to 200 (V = 2.0m/s) the calculation diverges. For a cylinder I believe Re = 200 may be indicative of the start of transitional flow, so would the laminar setup of this case be expected to lead to divergence, or are there other solver settings that I could change to converge this case for Re = 200?
You should also increase the resolution in this case.
