Reply To: resolving BL in openlb


Dear Ryan,

thank you for your feedback. The written value is not correct and the functor will hopefully replaced in the next release. We are not able to resolve the flowfield entirely. You can have a look at the laminar/poiseuille3d example, there you find a working calculation of the wall shear stress. The criteria to decide if a boundary layer is resolved, are the same for LBM and FVM. Unfortunately, OpenLB does not feature grid refinement at the moment. So it is hardly feasible to address wall-resolved LES at high Reynolds numbers.
