Dear all,
I am trying to make hexa mesh for the DTMB hull using ICEM CFD, for different case study, I will use FLUENT as solver, The main problem that I have a negative elements and the angel is zero, I tried make O grid in the stern check double vertices,no solution!! I did the main blocks and every thing seem to all right except those elements, I am trying since 6 months to find solution before I decide to post, I appreciate your help,if you have experience how to solve it or if you had same problem please share the solution with me. |

Could you share a quality histogram and some screenshots of the region with problems?
If there is a zero angle, there might be the chance that you squashed a block. Such block would have almost zero thickness, und would look like a thin layer when you display only blocks. |

Thank you for your reply,

You obviously know about scan planes. Investigate that region with bad elements further, and maybe share screenshots from a couple of different views.
Investigate how the respective blocks are formed. Why deviate they from the optimal cube shape. Which edges intersect others. |
