MRF mesh generation using snappyHexMesh
i used to create cell zone by setSet utility but, results of simulation came not goodPosted December 29, 2017 at 06:00 by ruikeradity1

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?

Ok, I get it. Thank you very much!Posted November 22, 2011 at 13:24 by Anneg

MRF mesh generation using snappyHexMesh
Hi,
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.Quote:Originally Posted by Anneg
Hi Amgode,
I've been trying to do the same than you, and I understand the strategies you propose to use snappyHexMesh with MRF.
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?
Anne
BC need be specified on the mrf boundary.

Hi Amgode,
Besides, is the mesh quality good enough at the interface between the stationary/rotating zone?
Anne
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.
