fluent shows that the the interface zone overlap
 
hi
everyone . I was simulationg a centrifugal fan ,and i decompose the fan into threeparts: the inlet zone ,the blade zone and the volute zone ,and the zones were connected with interface. when i initialize my case ,fluent show the warning message:

Info: Interface zones overlap for mesh interface in2.
This could adversely affect your solution.


can somebody tell what i shroud do ? or what the message means ?
thanks!

I have the same problem... Did you find out what was wrong?
Please advice

Can you please tell me what you did to get rid off this error

First of all it is not an error. Rather a warning or information as it suggests. It merely means that the meshes on the surfaces sharing the interface are not matching. The only way to overcome this is to enforce 'matching' (on the surfaces sharing in the interface) during mesh generation

Hey Vasava
Can u please tell me how can i enforce matching?

In anys meshing, you can right-click on the 'Mesh' and select 'Match Control'. Then select high and low faces. Also select 'Axis of Rotation'. Thats it!!

And in ICEM, for a mesh that is already ready?

control maching
 
hey mila.d.b
yes for mesh that already is you enforce control maching
right click on mesh---->control maching. then choose the faces you need to mach the mesh and an axis then generate mesh agian.
thats it

hello guys,

i am experiencing the same problem, did anyone solve this problem yet?
please help

sliding mesh in train aerodynamics
 
I am working on Effect of wind pressure on electricity poles along the train track lines induced by the movement of high speed trains. I have created my train model and the electricity poles. I created the first boundary condition which contains only the train model and I also created the second boundary condition that contains both the first boundary condition and the electricity poles. I used this method because the train is in the dynamic region (sliding mesh) while the electricity poles are on the static region. I created two inlets and outlets with respect to the two boundary conditions am using.
My question: I want to implement sliding mesh but I did not see mesh interface in the setup tree and my structured mesh didn't fail. How can i activate the mesh interface in my fluent model?
Thanks
