Mesh gets worse to the outside of the object
 
4 Attachment(s)
Hi,

I'm beginner in creating Meshes with sHM and my first steps were okay i think ;). But now i have a Problem. No matter what i do, the Mesh is fine near the symmetry plane and gets worse to the outside. I already tried different settings in the snappyHexMeshDict, but so far nothing really helped. I attached my snappyHexMeshDict, the logfile of snappy and some pictures that may help to understand my problem ;)

I hope someone here can help me !

Regards,

Iko

Upload the case using dropbox or google drive or something similar I think that will get you the fastest help.

Your sHM log at some point says:

Code:

Did not succesfully snap mesh. Giving up.
So you don't get any snap to the surface.

Don't know how to solve this but it may point you to the right direction…

Thanks for your help, I just solved my problem :)

I didn't declared the symmetry plain as a symmetry plain in the blockMeshDict ...

After i did that everything went fine !

Thanks a lot !
