OpenLB – Open Source Lattice Boltzmann Code › Forums › on OpenLB › General Topics › Inlet velocity profile › Re: Inlet velocity profile July 19, 2018 at 4:36 pm #2890 tartopommMember So I added that line just before setting the slip boundary: sLattice.defineDynamics( superGeometry, 2, instances::getNoDynamics<T, DESCRIPTOR>() ) but again, it didn’t change anything, did I miss something? Thank you for your time!
