Jan 19,  · Hello, I have some hydrodynamic waves reflections on the outlet of computational domain using outlet pressure boundary condition so I decided to implement the non reflecting boundary conditions in our in-house code which is incompressible navier-stockes finite elements/spectral code because we will use the aerodynamic sources to compute the radiated noise in the aeroacoustics . Non-reflecting boundary conditions mean than acoustic waves travelling towards the boundary condition surface will not be reflected by this surface, but numerically absorbed. Non-reflecting boundary conditions applicable to general purpose CFD simulators Article (PDF Available) in International Journal for Numerical Methods in Fluids 28(3) · September A non-re ective out ow condition can be obtained by cancelling out the incoming waves, thus by setting L. 5 = 0: (14) However, this latter condition can lead to a drifting mean pressure, because the boundary condition has no indication of the target pressure to reach. ECCOMAS Congress VII European Congress on Computational Methods in Applied Sciences and Engineering M. Papadrakakis, V. Papadopoulos, G. Stefanou, V. Plevris (eds.) Crete Island, Greece, 5–10 June CONSISTENT NON-REFLECTING BOUNDARY CONDITIONS FOR BOTH STEADY AND UNSTEADY FLOW SIMULATIONS IN TURBOMACHINERY APPLICATIONS. NON-REFLECTING BOUNDARY CONDITIONS 19 Smith [78] shows how the reflections from a piecewise planar boundary ae can be eliminated by adding together the numerical solutions of several problems, in each of which a certain combination of Dirichlet and Neumann boundary condi- tions is Cited by: Non-Reflecting Boundary Conditions in OpenFOAM. There are two approximate non-reflecting boundary conditions available in OpenFOAM: where \(D/Dt\) is the material derivative and \(\boldsymbol{U}(\boldsymbol{x}, t)\) is the advection velocity. Sep 03,  · Non-reflecting boundary conditions. The boundary forms a pressure outlet with a fluctuating static pressure being applied at an opposing pressure inlet. The problem I am having is that the solver diverges almost instantly. I have reduced the courant number and the relaxation constants however non of these seem to stop the divergence.
