Hello, I have problem with my case. I wrote vertices and hexes and when I am trying to make faces I got alot of errors.

I want to make a small cube inside bigger one. The small cube is a plate and its not moving so I singed wall type.

[root@archlinux:random]# paraFoam -block
created temporary 'random.blockMesh'

Creating block mesh topology


--> FOAM FATAL ERROR: 
Trying to specify a boundary face 4(21 25 41 37) on the face on cell 10 which is either an internal face or already belongs to some other patch.  This is face 0 of patch 0 named plate.

The error says that face is connected to other face. I am using OF-2.2.2 and paraview-3.12.

I don't think it's possible to create internal patch definitions using blockMesh directly. I'd suggest creating your topology first and then using topoSet to create a faceZone which then may be conveniently converted to an internal patch using createPatches. Have a look at the propeller tutorial in $FOAM_TUTORIALS/incompressible/pimpleDyMFoam/ to see some examples.

Peace,

Thank You for your time. I have already solved issue, just didnt mentioned here
