Unwanted wall boundary in the interior...
 

Hi!

I'm new to openFoam but I have been trying to figure this out for a while. Can someone please help?

I am trying to generate a box shell (outer box with dimensions 6 by 6 by 10) and inner dimensions (5.5 by 5.5 by 10).

I have attached my blockMeshDict file, Geometry generated (of1.jpg), mesh generated (of2.jpg), and erroneous wall patch (of3.jpg).

What this does is it prescribes wall boundaries in the interior of the problem which isn't correct. I need to fix it.

Initially I tried to specifically specify faces with walls - no slip. But that gave me error of no neighbouring cells. I tried changing the ordering of my vertices with face definitions but it kept on giving me the same error. I have that commented out in the blockMeshDict file.

If someone could please help, I'd be really grateful.

Thanks,
Japan
