    MRF mesh generation using snappyHexMesh

    i have read MRFZone.H and it says that faceZone can optionally be used for MRFZone.

    normally in the tuorial they just use the cellZone.
    when is the case faceZone need to be defined for the MRFZone?

    thanks

    But in the first solution, if you create a cylinder that you use as a refinement surface, don't you have to specify a boundary condition on that cylinder? Which kind of BC do you use?

    The MRF is not available as a boundary (it will appear in the boundary file with zero faces and can be removed for simulation purpose)but as a faceZone and a cellZone.

    BC need be specified on the mrf boundary.

    The quality of the mesh generated using OF-1.7.1 is pretty good. Moreover, with OF-2.0.x the quality is good as well as the edges are captured when the featureEdge capability in OF-2.0.x is used.



    Hope this helps !!!!

    Thanks for your inputs on that topic.
