hi,guys!I am useing sliding mesh to simulate the relative motion between the trian and tunnel.it is easy to converge,but the result is beyond my imaging,and wrong.attached is the fluent model and result contour.Any suggesiton or advice is appreciated.

Hi Shiren,
Please post more details of your problem like the train speed, type of mesh and other details about the domain (model details). Why are you using sliding mesh ? Raashid |

Thanks ,Raashid.The velocity is 350km per hour.The attached are pictures of local mesh aroun the nose shape,and boundary set.If more information is needed,please feel free to email to shiren77@gmail.com.

Raashid,sorry to forget you question.I think sliding mesh takes less time than dynamic mesh.you know,I am doing research on nose shape optimization,which need lots of analysis,so I prefer sliding mesh.
