turbulence in a pipe
I am doing turbulence of a pipe now, but I have got two problems in meshing. the pipe is one-meter-long with the diameter of 50cm. the mesher sent the warning message 'aspect ratio >50',and I tried to reduce the default face spacing,but no improvement. and then I tried to add wall as face spacing.but still I got this warnig . Another thing is about the inflation layers,I set it for 30,but I am not sure.Can somebody please give me a hand? many thanks.

Re: turbulence in a pipe
Hi,
If the aspect ratio warning applies to the inflation layers then you can probably ignore it. If the elements are aligned with the flow (and with nice inflation layers it is) you can still get accurate results with quite high aspect ratios. Glenn Horrocks |
