Hi,faraz
i didn't get what do you mean:( sorry.
i put my blockMeshDict and the checkMesh files in the following, would you please tell me again.
thank you very much.

Hello S.m please try to upload some pictures of your background mesh here .. ill see. actually the faces your have mentioned in blockmesh are those which you need for your case. but in order to avoid the given error , you always have to define all the remaining faces of sketch or drawing in blockmesh ... no matter your need those faces or not. may you get it?

Hi faraz,
i put a screenshot of my mesh with it's patch name. my background mesh is a domain with inlet outlet top and bottom after running the snappyHexMesh i 'll have this mesh that i upload here.
i put my block mesh also, i want to know what should i add to my blockMeshDict ?

This is not the case with your mesh and that is why your 2D simulation does not converge and checkMesh complains about those edges.

Hello Jens, can you tell me how I solve this because I'm having this problem right now.

Thanks

Luis
