Reply To: Issues with Geometry Selections and Local Sizing in ANSYS Fluent

[Paul Stephen]

 

Hi, 

I am using the Ansys 2023 R1 version. Do I need to try with R 2 version?
I would also like to bring your attention to one more issue:
Geometry and Boolean Operations: In my study, I created a flow domain around the geometry, and I performed boolean subtraction/suppression operations successfully.

Meshing Issue: After importing the geometry into Fluent for meshing, I noticed that just after creating the surface mesh, the console window displays a message stating, “The region consists of 1 Fluid and 1 void region.” This differs from the examples in the Ansys innovation courses, where only one fluid region and no voids are expected.

Comparison with ANSYS 2020 R1: To verify, I performed the same procedures in ANSYS 2020 R1, and I obtained the expected result mentioned in the innovation courses, i.e., “The region consists of 1 fluid region with no voids.” However, when the same file is transferred to ANSYS Fluent version 2023 R1, the message window still identifies 1 fluid region and 1 void.

I would like to know whether this is because of Ansys versions or Do i need to take of all this.
When I ignored the console message and proceeded with describing the geometry I had one only 1 fluid region. I received a warning message in the console window” The region cannot cannot be deleted as it is completely enclosed by another region”.
