Re: About ConvectionBC


Hi steed188,

first we several pressure boundary condition approaches local and interpolation. I don’t know which one you use for your case. I prefer interpolation because the non equilibrium bounce back approach will be instable by high Reynolds numbers. If your geometry has an inlet and outlet of the same size, you should use periodic boundaries. I actually working on wall functions. OpenLB will get this feature in the future. If you want to learn more about simulating turbulent flows with LBM, I highly recommend you our spring school in March.
