Hi everyone!
Is there any possibility how to mesh T-pipe only with cooper? I want to mesh DN 700 pipe connected with DN 400 pipe in "T-shape" Thanks! |

This is not a T-Pipe, but you can get inspired from it

Ok,
Then make a volume decomposition like this: Capture.JPG Capture1.jpg Be sure to start meshing the red volume

copy those lines in text editor and save it as text.
Then in Gambit you pick this file to run the journal: File>Run Journal...

do you mean automation?
It was possible on Fluent 6.3 Now I don't know

open case 1
run case 1 write case and data for run1 open case 2 run case 2 write case and data for run2 open case 3 run case 3 write case and data for run3 ... the computer does all the tasks automatically

Because, if I run this journal in Gambit 2.2.30 it show me an error on this pic model trial.jpg I am almost done, but I do not know, how to split this last red volume (( m?j model.JPG Thanks a lot! |

ok in your case I think you don't need to do another split.
You only have to enforce gambit to choose cooper scheme, and select source faces for cooper. Here choose the 3 surfaces as I mentionned in the picture Be also aware you need to mesh this volume first, and all other after: you will project mesh from blue surfaces, on red one. If red surface is already meshed, Gambit cannot project mesh on blue surfaces, because it has do generate a cut in the mesh Capture.JPG

I almost done it, but couldnt mesh the last volume... I will do my whole project in tetrahedra and convert to polyhedra. Numerical time will be longer, but just thinkin, that I have to dothis for all T-pipes makes me cry almost done.jpg |

Then Apply Tet/Hexcore, it fill fill the domain with a max of hexa in the core of your volume.
But you will have to delete all the splits in the T-junction, else you will enforce the presence of tetraeders on the split surfaces
