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!

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?

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

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

can anyone tell me how to solve this problem using Icem

Interface zones overlap for mesh interface interface.
This could generate left-handed faces on the interface and make it invalid for use.

In Ansys fluent setup-Mesh interface- Enforced is there.

I have activated this option but unfortunately this option only applies to flat surfaces and at the same time no more than one surface can be selected (if the upper and lower surfaces consist of several surfaces) in this option. Is there another option to match the surfaces in this case in ANSYS FLUENT.

I had overlapping problem for several days and here is how I fixed it:
My geometry consisted of two parts (a sweep and an extruded with a sweep cut) and I had designed it in Solidworks. At first, I noticed that the surface area of my parts’ contacts are not equal. Therefore, instead of swept cut, I used “subtract” in “combine” section in Solidworks to design my second part, and have equal contacts. After importing my geometry into Ansys Workbench, I shared my geometry in Spaceclaims as to have one part that includes all my bodies. In Ansys meshing, since there is just one part, contact areas would have same mesh size and type and no overlapping.

hey @nwadikeamarachukwu@yahoo.
a bit late to reply ,but you go to "Boundary Conditions" then you choose the boundaries that consist your interface and you select "interface" .
Having done that you will be able to see "Mesh Interface" on the "Setup" tree ,so you click on it and create a "Matching Interface" .
