hey everyone,
I made a structured mesh for a 2D geometry. associations are done, conversion to unstructured is done. when i export, it's telling me that it has uncovered face. i don't know where does it come from and then fluent can't open it. Can somebody take a look at it ? Thanks a lot https://dl.dropbox.com/u/35161486/me...d%20intake.zip |

Hi Ali
When I used the tool "refinement" for one of blocks, I had the same problem as you, ICEM CFD version is 14, but my friend operated in the same steps in version 12.1, or I didn't use this tool "refinement", there is no problem, I want to know weather yours is version 14. |

I had a look at your file.
Some of the edges, including outlet and solid, do not have associations. This is causing the uncovered problem. |

thanks a lot. your blocking strategy is better. i have few question tough.
the blocking i did, was nearly impossible to do it in one shot. i had to create separate blocking and merge them. how about yours, did you modify mine or start from scratch ? did you do it in one shot ? |

I started from scratch and completed in one go. For this I had to make four to five horizontal splits (spliting vertical edges) and then deleted unwanted blocks permanently and then merged vertices to get the sharp corners in front part. Since in the front part after vertex merging I had 2d triangular block and I had to convert it into y-block. But problem is that Y-block command is not available in 2d, so I converted blocking into 3d by option 2d to 3d with depth (z direction) of 0.3. Converted the triangle block into Y-block and again changed the blocking from 3d to 2d and deleted all blocks out of x-y (original) plane. PS. This idea came from my experience of meshing Fan, low pressure compressor and by pass duct using Gambit(R). |
