Hi,

For the same reason that was stated previously in this post:

https://www.cfd-online.com/Forums/op...tml#post659309

You cannot have an arc show up when you have only 1 cell.

Cheers,

I made 4 cells like you said, it isn't just 1.

[Antimony]

Hi,

This line indicates that there is only one cell (the section that has been indicated in bold)

hex (0 1 2 0 5 6 7 5) (1 1 1) simpleGrading (1 1 1)

It should read something like this

hex (0 1 2 0 5 6 7 5) (1 4 1) simpleGrading (1 1 1)

I have changed the number of cells/divisions to 4 on the line connecting vertices 1 and 2, which is where one of your arcs is.

This should help clarify.

Cheers,
Antimony
