Im doing a volume mesh in my geometry. It consist in 5 NACA profiles in a rotational domain. The local sizing in my turbine that is modeled as a wall is 0.85mm and the local sizing at the sphere wich is my domain is 16mm. The minimum space between those elements is 50 mm. 

Im having a lot of problems doing the volume mesh: SIGSEGV(segmentation violation) , Error: Volume meshing was not successful, likely due to unresolved gaps. Edit the Create Volume Task and in Advanced Options, set Check Self Proximity to 'yes' before re-execution.

What can i do to resolve those problems?

Hi Juan,

To easily identify gaps in Fluent meshing, the best approach is to apply shared topology within Fluent Meshing. Start by enabling the "shared topology" option in the "Describe Geometry" task, which automatically adds a new "Shared Topology" task to your workflow. By selecting the "Mark Gaps" option, you can visualize any unresolved gaps in the model that may be causing mesh failures.

Alternatively, you can remove gaps directly from the "Outline" tab. Simply right-click on the mesh object, navigate to "Advanced," and select "Remove Gaps."

For more detailed information on the "Remove Gaps" option, refer to the section 10.5.2: Removing Gaps Between Mesh Objects in the ANSYS Fluent User Guide: 10.5. Advanced Options (ansys.com)
