Problem with a nozzle and ambient volume
i'm trying to mesh a nozzle connected to an ambient volume; you can see the geometry pic attached. The nozzle have a small injector connected in the divergent. In the pics you can see the actual blocking and the premesh.
I have managed to mesh the nozzle correctly using an O-grid, but i'm not able to mesh correctly the front faces of the ambient volume; as you can see in the premesh pic, i have several distorsion. Is there a way to mesh the front faces?
It's always difficult to give a good advice without .tin and .blk-files. So it would be very helpful, if you could supply them.
But one for sure: you've to insert another o-grid to resolve circular shape of the outer volume.
I can't see the details, you're talking about on your pics. So please supply the files or give us some more detailled pics.
here is the file.
thank you for the help!
You have problems in the outer volume and in the injector. I tried to make the o-grid but unsuccessful.
Some advance blocking techniques were needed to get this mesh.
Like creating three o-blocking, deleting few blocks permanently and few without permanent option. Deleted middle o-block, merged vertices, some were not merged. Extrude along curves option was also used.
You can further improve quality by adjusting edge mesh parameters and vertices.
you've done an amazing work here, thank you very much for the help!!!
i'll try to replicate your work; in case of problems, i'll ask here for some advice.
thank you again! =)
You can use your old blocking effectively if you change your outer domain into rectangular shape. Every will be perfect !!!
I am also attaching the intermediate blockings so that you can understand where to start and what to do step by step. Especially pay attention on blocking 3 and blocking 4 where I made three O blocks and deleted middle o-block. b
Also 5 to 10 where I am performing merge operations and association to edges. Blocking 12 with extrude along curve for. Compare blocking 10 with 12 inside the nozzle.
Do not follow blocking 17. First I tried to make the blocking in the injector. Then I deleted and instead first made the o-blocking in side the nozzle and carried into towards the far-field. Then extrude the blocking for the injector pipe and then made the o-blocking for the injector. Got it???
Hope it helps. :rolleyes:
