Blocking a triangular surface

I'm blocking and meshing a domain depicted in the figure below. The two rectangles and the triangle with a fillet in the tip are not included in the fluid zone. My problem is that I haven't managed to create a satisfactory mesh for the domain near the triangle surface, there are some non-orthogonal faces.
I've attached pictures of my current blocking and mesh. I'm sure that this is an easy task but I just can't figure it out. |

Hi,
Your mesh (3rd picture) looks bad... the triangle looks like a pyramid, did you assign all edges to the curves? Some of the quads are "cutted" at the edge of the triangle. Anyway: If I recall correctly, user "far" showed a good blocking for triangles in some thread, maybe that helps: triangle meshing.png

Thanks for replys. RodriguezFatz: yes, I did assign them. I also found this video a few days ago http://www.youtube.com/watch?v=92vScop7b8Q but didn't manage to get things working.
Anyway, I will be out of office until Monday but will report my results after giving it another try. |

But what about the triangular faces of the middle body? He needs to mesh the front and back of it.
@esgee: Did you cut the middle body, or why does the screenshot of the grid look so strange?

Doesn't that depend strongly on the way the flow takes, i.e. on the inlet and outlet positions?

Hi guys,
Iīve done a quickly blocking. I think this blocking can be improve better, maybe this block is similar to Philippīs idea. Anyway, if anybody want to try I give you the geom here! https://www.dropbox.com/s/heej79l4v9...riangleBox.rar |

Hello again. I tried to apply same approach as FJSJ but my grid is still bad.
e: I finally managed to solve it. Thanks for your kind effort. Last edited by esgee; May 28, 2013 at 07:54. |

well, itīs not my approach, in any way, it would be Philippīs approach. Anyway, this is not the best blocking. Farīs idea is the best, at least, I think so. But I would see some picture with blocking edge, like Philipp did.

Thanks you for explaining the blocking with the O-grid!

3D Wing

Hi Far
I have to mesh the fluid around this 3d Wing. As you see i have a complex 3D Wing and i have to mesh it, the problem is the vertical part of the wing and as you see here i have splitted it to 3 parts. To have a good mesh i need to split the left and right Blocks to Blocks with triangle Surfaces to fit with the parts of vertical Surface. Could you please give me an idea to do that or mesh it? Thanks |
