Virtual Outlet

Hello,
Where can I find a documentation on the outlet boundary condition ‘Virtual Outlet’ which has been used in the code Moving Walls? I am working on a 3D rotor LES study using Palabos based on the generalExternalFlow code, and I was wondering if it could be used as an outlet condition, however I can not find any information on it.
Thank you,
Deepali

Hello,

For LES I would recommend FluidPressureOutlet3D as an outflow BC. You can see the generalExternalFlow example to find out how to use it.

Information on FluidPressureOutlet3D and VirtualOutlet can be found in the file:

palabos-v1.5r1/src/boundaryCondition/neumannCondition3D.hh

Best,
Dimitris
