For some reason, your patch merging has failed. Try switching on debug for:

polyTopoChanger
polyMesh
enrichedPatch
slidingInterface

and see what it says.

Look at ~/.OpenFOAM-1.3/controlDict

If you haven't got that, it will live in the .OpenFOAM-1.3/controlDict directory of your installation.

The mesh checker reports 12 open cells found. Max cell openness: 2.8744 and Failed 3 mesh geometry checks even before you try coupling the mesh interfaces. This is not good - you should make sure the blocked mesh is correct before you continue.

You´re right. Should fix whatever I messed up in the ordering of the nodes of the faces that I want to merge. To start with...
Will let you know whether I sort it out.

Hi again,
I went back to the blockMeshDct file and re-defined correctly the order of the nodes in the patches to be merged. That meant that I got rid of the open cells but I am still left with the same sort of problem.
I will just quote the error messages from blockMesh generation:

HI,
I think Hrvoje answered this, something like you cannot do two mesh modifiers at a time...as in the patches that you want to merge are intersecting..so you probably have to do one direction first and then with stitchMesh the remaining pair.
Am I right, Hrv?
If I find what I did sometime back I will post it here

Hello Message Board,

I'm trying to use the function mergePatchPairs in order to solve the problem of hanging nodes.

The case can be described as follows:
Originally we have a closed channel with a square cylinder positioned vertically to the flow direction and is mounted on the front and back wall of the channel. In order to derive adequate results I'm defining several domains around the square cylinder becoming coarser from the inside to the outside domain.
___ ______________ ___
|___|_______1______|___|
|...|_2_|___3__|_4_|...|
|...|...|square|...|...|
|...|...|cylind|...|...|
|...|___|______|___|...|
|___|_6_|___7__|_8_|___|
|___|_______5______|___|

For this reason I'm defining a patch combined of 2,3,4 and merge it with 1 and also doing so for 6,7,8 and 5. That works fine!

BUT if I try to merge in the same principle in vertical direction, I receive the following error:

--> FOAM FATAL ERROR : Error in point ordering: mixed used and unused points at the end of point list.
Number of used points: 281841 and point 282051 is used by a live face.#0 Foam::error::printStack(Foam::-Ostream&) in "~/OpenFOAM/OpenFOAM-1.4.1/lib/linux64GccDPOpt/libOpenFOAM.so"

What is going wrong here?
Is supposed, that there might be some problems on the corners that might be twice involved in merging (one time horizontal, other time vertical), therefore I changed the master to the slave patch and the other way round. but that didn't solve the problem either...

So please give me a hint!

Any help is appreciated!

Please excuse the bad picture

hi everyone. i was trying to create a mesh around a solid cylinder.
can anyone suggest me which will be the best way? as im new to
openfoam, i started with quarter part of the whole mesh to be
generated containg the quarter of the cylinder. i did it in
blockmesh...while executing it, i was finding the following errors.
can anyone suggest me what might be the bug in here?

hi all.

the above problem i have posted was resolved but i have some other.

i have 4 blocks to be merged in a particular manner.
i have named the walls which are not to be merged with any other faces as 'patch0'(patch followed by a number representing the patch number). And i have named the patches which have to be merged as merge01-1 for example for the face which is involved in the merge between a face of block 0 and another face of block 1. and the last number '1' says that the face is belonging to block '1'. So this is the following blockMeshDict file obtained: (please look for problems in mergePatchPairs in particular. coz if i delete either second line or third line in mergePatchPairs, it was working fine at the cost of not being able to merge that deleted merger)

HI,

I am facing a problem while creating a mesh for a deflected airfoil. I have built the mesh in simple blocks. CheckMesh does not display any error but when I run icoFoam, I get the following error

This mesh contains patches of type empty but is not 1D or 2D
by virtue of the fact that the number of faces of this
empty patch is not divisible by the number of cells.

I had this error previously and it was due to defining an internal face at the boundaries. I have already checked for this error. It is not the case this time. Then individually all my blocks are fine and are 2-D. But when I run this file with blockMesh I get the message of 3-D mesh with refineMesh. For you view I am attaching my file with this mail.

Can somebody please help?
