Mesh problem
 
1 Attachment(s)
Hi everybody.
I'm performing a thermal analysis on Fluent and i have a problem about the mesh.

In the figure i uploaded you can see that the mesh lines on the external disk are just inclined with respec to the one of the internal, which are towards to the radial direction.

How can i make also the external mesh lines radial?

Thanks in advance

most likely, if you have same points amount on internal and external circles it will solve your issue

Do you mean the same number of division of external and internal circumferences?
If yes, i'm doing so, but the result is that one
if no, could you explain better?

Chop both cylinders into four 90 deg sectors and use hard sizing based on the number of divisions.

yes I mean that.

you can use face meshing on face with problem.
also you can use multiZone as a method in case of 3D
