Mesh Failure

Hi,
When I try to mesh my geometry, it always fails and I keep getting an error saying that tetrahedral meshing failed because some of the faces have less than 3 boundary nodes which prevent them from being meshed. On inspection, I find that these faces are really small and are almost like straight lines. Whatever I did to solve the problem like merging faces, or dleting them altogether didn't work. Can someone help me fix this problem? My original model wasimported from Pro/E. Thanks, Vidya |

Dear Vidya,
Select the faces that have less the 3 boundary nodes. Mesh them separately using a fine mesh and then try meshing the whole volume by switching off the remove old mesh option. Good Luck Sundar |

Hi Sundar,
GAMBIT crashed when I tried to do that. Is there any other way to fix the problem? Also, when I tried to mesh thise faces separately, 2 of them were meshed with highly skewed elements (Equisize skew> 0.97). And the third face also had had a very skewed mesh. Then while meshing the volume, the program crashed. Any suggestions for this? Also, I do not find any way to repair the bad geometry (edges, angles). When I used the clean- up operations, they failed too. Do you have any takes on these? Thanks, Vidya |

Hi Vidya,
Will it be possible for you to send me the geometry? Do you have any messenger so that we chat across to fix the problems. Sundar |
