Hallo,
I´ve created a mesh and checked it in tgrid. During the checking-process a prompt-message appeared: "left-handed-faces" After this I get the message: "Check mesh failed" How can I fix this problem and improve my mesh? Thanks in advance Arnold |

Hallo Wanghuiru,
thanks for your reply. I´m not a professional in handling tgrid yet. Should I type in this command? I tried it, but there was an error prompt like: error: eval: unbound avriable error: Object ... First we should compare our versions of tgrid. I´m using tgrid-version 4.0.16 Actually I have no button called grid, modify or repair-face-handedness. Greetings |

Hallo Wanghuiru,
I did the command. I have to type mesh/modify/.. . But the command repair-face-handedness does not exist in my version of tgrid! I tried it in fluent, there I have this command. It seems, that the mesh is to bad. To remesh the geometry might be the better choice. Thanks for your help Árnold |

You need to make export double precision files. In the export preferences, change "single" to "double" for Export precision. This must be done before creating a mesh. You will also need to run Fluent in double precision Left-handed faces often occur when two dimensions are large compared to the third. Modelling cities and landscapes can produce this problem in single precision. |
