checkMesh fails after introduction of a cyclicAMI
 

Hello everyone,

I'm relatively new to OpenFoam and new to this Forum which means that i still has a lot to learn from you all, so thank you in advance !
For my case i'm using OpenFoam 4.1. I first load a fluent mesh which is rather a complex one with several interfaces and bodies (the same mesh works perfectly in CFX).
I use fluent3DMeshtoFoam to convert the mesh and it goes well and the boundary file is created with all the patches and walls i already had previously in CFX.
At this point, running the checkMesh was no problem at all and the log out of it is (first_checkMesh).

When i try to modify the boundary file to change the types of some patches to cyclicAMI i get the error attached as (second_checkMesh). Same error if i launch rhoSimpleFoam.

May be important to mention that originally all the boundries in the file boundary are only patch or wall.

I looked into some threads and the error seems to occur because the the number of patches in boundary does not match with the declared number of patches which i checked and is not the case.

I also attach my modified boundary file.

Your help is much appreciated !

The errors you face are dummy errors...you deleted some }) in some definition of patches...

In any case with first output, if I were you, i should consider to remesh, especially for the 22614(!!!) faces with higher non-orthogonality (>80). Further more even with few skewfaces and high aspect ratio cell, you can have problems...

Thanks for the reply.

I'am aware of the non-orthogonality problems im my mesh which will be one of the next steps to deal with.

I'm sorry but i still don't see where i missed the some of } or ). could someone point that out ?

Thank you in advance

Hi,

indeed the error message could lead to misunderstanding, but reading carefully, it tell us that an is missing.

Thank you very much, it was indeed a dummy error.
