stitchMesh : duplicate point
 
Hello everybody,

I have a problem using stitchMesh utility. When I want to stitch two interfaces i have a duplicate point error :
Code:

Duplicate point found in cut face. Error in the face cutting algorithm for global face 4(53292 53293 54193 54192) local face 4(0 1 2 3)
Slave size: 240 Master size: 917 index: 0.
Face: 10(53292 55407 55408 55092 55165 55164 55163 55166 54193 54192)

I can't find the answer on previous threads...

Hi Nolwenn,

I also got this error message. Have you figured out the problem? Mine two patches should be identical, I don't know where goes wrong...

Thank you!

Best,

Hang

stitchMesh
 
Hi Rebecca and Nolwenn,

I am having the same problem. Did you figure out a solution? I read on the forum, we should use a -perfect flag for stitchMesh, but when i used it, I got the following error message.

Quote:

--> FOAM FATAL ERROR:
Points on patch sides do not match to within tolerance 7.40161e-06

From function perfectInterface::setRefinement(polyTopoChange& ref) const
in file perfectInterface/perfectInterface.C at line 220.

FOAM exiting
My geometry is like a big block with two rectangular holes, where I am trying to insert via mergeMesh and stitchMesh, two solid rectangular blocks having the same dimensions like the holes.

Thanks,
Dhruv.

Hi Dhruv,

the -perfect flag actually worked for me. Are the two patches you are working on 100% the same? Maybe you can try other flags?

Best,

Did anybody find the solution for this?
I also get Duplicated Points and can't figure out how to get rid of them.

Thanks a lot!

Hi Dhruv,

I have right now the same problem trying to merge a rectangular block (1) into a mesh with a rectangular hole (2).
Bounding boxes of block (1) and hole (2) are identical, but points and faces at the interface are different.
The executed command is the following:

stitchMesh -overwrite -perfect INTERFACE defaultFaces


Did you find out a solution for the quoted issue?

The error reported in my case is the following:

Code:

--> FOAM FATAL ERROR:
Points on patch sides do not match to within tolerance 1.45655e-05

Thanks for your support,

Best regards,

Hello,
I get:

--> FOAM FATAL ERROR: Duplicate point found in cut face. Error in the face cutting algorithm for global face

when using stitchMesh. The interfaces are the same but with different resolution and complex cells. Any hints or maybe improvements with OF 2.3 ?
