Createpatch and SnappyHexMesh
 

So I created a blockMeshDict file for a quarter cylinder and create two patches there. Then I decreased the matchTolerance in createPatchDict and turned off pointSync and combined two patches to create a cyclic patch. But when I use snappyHexMesh I get the same error I used to get using createPatch (before I turned off pointSync and decreased the matchtolerance). The error is

face 0 area does not match neighbour 200 by 44.3085%.....

Im assuming a matchTolerance in snappyHexMesh would fix this but I dont see that keyword and when i try to run snappyHexMesh with the keyword it gives me the same error. Anyone encounter this before or better yet solved it?

Update - the problem above was solved by redefing the vertices so that the face areas are the same. But now when I run snappyHexMesh it gives me the following error -

Faces do not seem to be correct across coupled boundaries

Anyone know why this is?

Thanks!

Same Error
 

Hi hm86,

I'm encountering exactly the same problem as you had. And was wondering whether you found a fix for yours?

Thanks!
