Cyclic GGi Vs cyclic patch
Dear All
Will anybody explain what is the difference between the Cyclic GGi Vs cyclic patch.I am asking this because i have run my case with cyclic patch in OpenFOAM 1.7.1 and the same case is not running in OpenFOAM 1.5-Dev and giving error.But i resolve this problem in OpenFOAM 1.5-Dev by changing the patch conditions i.e.cyclic to fixed value. Please Help. Thanks In Advance. |

Dear maddalena

Dear maddalena
With the guidance of you only i have created the cyclic patch and will you please tell me changes should i made for cyclicggi in constant/polyMesh/boundary file. As i am not getting any perfect data on it otherwise i have tried for it.Please give me the directions. Thanks in advance. |
Hi.
I used to work with OF16 and used to used cyclic BC with the createPatch utility. Now I switched to OF16ext and I realized that the set up of cyclic BC are not longer the same as it used to. Now, I read thru the wiki http://openfoamwiki.net/index.php/Si...setup_the_case in order to set up my case. Everything is fine, but my only question is this: what do I have to specify as "zone"? My case is a simple rectangular domain where the left and right boundaries need to be periodic. I will really appreciate any help. Thanks |
Hello,

In any case, a zone is a group of points/faces/cells in your mesh that have a single specific propriety. It can be created in a wide number of way. In your case, I think you need a faceZone, which can be generated starting from the patch these faces belong to. How to create it? Type setSet on your terminal window. ;) Hope to be clear mad |
