I have a model that has cyclic symmetry, where my model consists of 1/15 of the total model.

Without using "Cyclic Region" I can apply a Refinement on a face just fine (image below).

 

Now I add a cyllindrical coordinate system and "Symmetry", but no "Cyclic Region" yet.

In the image below I used Graphical Expansion (beta option) to show what my mesh should look like after applying a cyclic region.

 

After that I add a Cyclic Region (image below), by applying a low boundary (red), high boundary (blue). I choose the cyllindrical coordinate system shown in the image.

 

After this, my refinement has a blue cross instead of a green check mark, and says "No, overridden" in the "Active" row (bottom left in image below). Comparing this image to the first image I posted, it is clear that the refinement has disappeared.

How do I use a refinement and a cyclic region at the same time? Why would the symmetry override the refinement?

 

Thanks in advance for any help.

Match controls are not respected with refinement or adaptivity. Cyclic region basically uses match controls to create identical mesh on cyclic regions.

One way you can try is using face size instead of refinement for this face.

Thanks for your response. I did instead use face sizing, but this doesn't have the same effect. Refinement also seems to lower the growth rate for elements connected to the face-elements. Face sizing only affects the elements directly connected to the face (and perhaps indirectly the size of connected elements, but not to the same effect). See the image below, compared to the one in my original post.

 

Can I use some sort of local growth rate to also affect elements around the face, like a refinement would? 

I have looked around myself, but couldn't find a solution. The link you posted requires me to log into the customer portal, which I don't think is accesible to students?

Thanks!

The answer to my question was to disable adaptive sizing, which allowed me to choose a growth rate for my face sizing.
