Fine, it was just I was getting O-grid blocks all around the external contour. Thanks.

How have you made this O-grid exactly? from block? from faces? Edges? vertices?

Thanks

Thanks a lot Pospelov! You have used the o-grid block option in the blocking tab, right? I also use to force some 1st layer thickness at the smoothing stage.

Thanks Far, my blocking is still running without any problem. It is very similar to the one you made for me. I'll let you know the results.

I've redone all the blocking again until I got no negative 3x3x3 determinant. I don't know why I can never execute the pre-mesh quality tool. All the same I's smooth it 20 iterations and exported it...

Hi Far,

Here you are my icem files. I haven't uploaded the .uns files cause they're pretty big.
I have similar problems with a bigger mesh (1.8Gb) so I'd like to know the process to fix it.

I have many negative 3x3 determinants, I don't know what that means, but I'm trying fixing it with the quality up to -0.7 which is the minimum value reached. If I put a positive value, i.e. 0.2, the...

I've just made all the geometry as it is rather simple. I'm trying now to improve the quality cause I haven't noticed before the Quality menu in the blocking tab. It's giving error messages like the...

I've ploted the negative volume elements, they are all in two blocks. I've redone the edge and vertex associations and remeshed, nothing changed.
I've tried to invert blocks orientations, and...

Question Negative volumes

Hi everybody,

I'm working on a 3D geometry of an inclined flat plate. I'm doing a hexa mesh as it is a rather simple topology. Before converting it into unstructured mesh (to export it to Fluent)...
