Reply To: Using example (cylinder3D)
Glad to hear that you were able to solve it. You can definitely increase the Reynolds number and simulate turbulent flows using LBM. Either using DNS or (more commonly) using a LES model such as Smagorinsky. See e.g. the turbulence/nozzle3d example case to get started.
Examples for high Reynolds simulations using OpenLB include 10.1016/j.buildenv.2021.107618 and 10.2514/6.2013-2573.
