MEsh for pipe

Can anyone share the "right" 2D mesh of the pipe(or duct) that appropriate for scientific calculation??

I don't understand your question..please elaborate.
There is no "right mesh" as mesh size depends on your model, so on your boundary conditions.
Just create mesh size accordingly to y+ value of your choosen wall function.

Thank you Daniele. Do you have any example of meshes that as you think are good for making calculation.(I need to make a simulation of a turbulent flow through a pipe, pipe should be standard, "usual" pipe). Sorry for my english, I'm not native speaker.

I can share it. Tell me dimensions of pipe (length and dia).

Have a look to the tutorial "Minor Loss in a Pipe Elbow" from Professor John M. Cimbala web site :

Oh it's great! I need a pipe of 25m length( diam is 1m). Thank you Far.

Dear laurentb
Thanks for http://www.mne.psu.edu/cimbala/Learn...of_modules.htm
I want to mesh turbulent axisymmetric 3d pipe . Could you help me how build 3d pipe using GAMBIT

hi ,

I was out of station. Shall send you mesh within few days.
