Hi, I need to use unstructured mesh in a portion of the Leading Edge of a compressor blade cascade. I used a free block, imposing only tetra inside. The problem is that close to the leading edge, the elements grow up, without keeping the height of the structured mesh (calculated to meet the y+ requirement).
Ho can I do to have a similar distribution to the structured mesh? I enclose 2 snaps of the area. |

In ICEM CFD, you cannot match tetra/prism with blockstructured mesh. Ok, you can do so, but then you cannot have a height over base of the complette layer more than 0.49 leading to very high volume change. You can merge this grids in ANSYS Meshing, but why do you want to use a unstruct. mesh at you leading edge? My experience is, that a C-Grid should be the best was of meshing this. But you have to handle the round leading edge. |
