Hi everyone,

I'm trying to rotate a cylindrical domain (containing a Vertical Axis Wind Turbine) within a cuboidal domain and am having trouble with the mesh interfacing as there are still some pretty significant gaps between the mesh of the cylinder and the rest of the domain.

I've tried putting the two zones into a single part and sharing topology, alongside reducing the contact size, and increasing the facet quality to 10 in designmodeler however there are still gaps which are impacting the flow around the interface. I've also tried connecting using designmodeler and doing a contact match in meshing but those caused problems with the dynamic mesh once I got into fluent.

Any ideas on what else to try? Thanks!
