Fluent geometry adaption issues

      Hello,

       

      I'm following up on a question I'd asked on my feed by mistake instead of here (https://community.ansys.com/?status%2F38737-38737-1658803739%2F#comment.3087.126871.126871) that Keyur Kanade responded with "Fluent will not capture geometry curvature as it does not have geometry curvature information. It works on existing mesh."

      The manual seems to suggest otherwise when you look up the geometry adaption Theory Guide (screenshots below). I'm trying to understand how what I'm doing is different from what I've been reading. I have a background fine mesh. Nodes are supposed to be projected to get towards the background mesh, as suggested. What am I missing? How do I ensure curvature information is passed on to Fluent?

      Hello, 

      As mentioned before, Fluent will not capture geometry curvature as it does not have geometry curvature information. It works on existing mesh. The image in documentation is representative. We will inform documentation team about this.

      So the information in the documentation is incorrect? This particular part of the documentation has been up since Fluent version 2019...

      There is nothing I can do to accurately depict the curvature of the geometry through the adaption mechanism?

      Yes, this particular image is incorrect in documentation. To capture curvature accurately, you will need to go back to geometry and meshing.

        So if I have a fluent solution marked with certain cells for adaption, how do I import that to meshing to perform adaption with ANSYS meshing?

      You need to start from geometry and not mesh. The mesh has already lost curvature information.
