Remeshing in Fluent Icing

      I am continually failing to generate a new mesh with Fluent meshing despite following the commands.

      The only error I receive in compiling is "This appears to be a surface mesh" otherwise the .jou file continues until the mesh fails to generate. 

      One thing to note, my institute has a Fluent icing license and not FENSAP itself. Is this part of the issue?

       

      Thanks

      Hi, 

      The issue is arising during meshing stage. Please review the file that is provided to the fluent meshing. Probably the correct input file is not provided.

      To debug the cause instead of using the journal file open a standalone fluent meshing session and redo the step as is prescribed in the journal. This will help you figure out the issue.

      Regards

      Omkar,

       

      Thank you for the advice. As I become familiar with the remeshing process, I have found myself able to remesh in 3D. However, doing so in 2.D is causing issues. 

      Let me provide some context in order for your best to advise. 

      I am using R23R2 and my files are .cas 

      First is my trial 3D run, where you’ll be able to see that there are 2 elements to the airfoil.

      Secondly I am aware BC naming is important and  I have followed suggested convention although I'm not sure if it should be wall-5 etc...

      With regards to the material point I have place this at the TE at the half-span location. Attached were my meshing parameters

      One potential pitfall is my mesh is not EXACT on z=0m, could this be an issue?

      Update on this part –  I tried a translated mesh with z=0m and this did not solve the issue.

      therwise what should I consider to ensure the 2.5D works as the 3D did? Happy to share comparisons of console output which cites the 2.D case failing due to there being no regions computed?
