11 дек. 2007 г. · I am trying to simulate a jetflame. Unfortunately I still have inflow in the area of the cowflow using inletOutlet for a cowflow velocity below 1.5 m/sec.

14 сент. 2011 г. · inletOutlet switches U and p between fixedValue and zeroGradient depending on direction of U is choosing fixedValue for p and U when the direction of U is ...

9 янв. 2020 г. · I am wondering, what would be the appropriate outlet boundary conditions for the velocity, pressure and alpha phase in this case?

12 янв. 2018 г. · This is a neat way to fix the problem you're facing in Fluent: An outlet boundary defines a zero gradient, independent of the flow direction.

16 июн. 2022 г. · Hello, I don't really understand the difference between the boundary conditions put at the outlet between 'inletOutlet' and 'zeroGradient'.

1 февр. 2006 г. · At the first iteration OpenFoam doesn't know if the boundary is an inlet or an outlet, so it needs some initial value to start the simulation.

4 апр. 2018 г. · Dear Foamers I am trying to get your attention to this age-old problem of inletOutlet boundary conditions.

16 июн. 2015 г. · If you want to set the pressure at the boundary, then using pressureInletOutlet can let you have a velocity vectorfield that is well defined ...
