请问:这个错误要怎么改正啊?? 谢谢了

Initialization failed; perturb boundary nodes and try again.
Initialization failed to mesh 4 nodes.
ERROR: TG_Mesh_Domain failed with error code 1.
ERROR: Tetrahedral meshing has failed for volume volume.2.
This is usually caused by problems in the face meshes.
Check the skewnesses of your face meshes and make sure
the face mesh sizes are not too large in areas of small gaps.

我也有这样的问题,就是划不了体网格,我想可能与模型的里面有小面,尖角有关吧!但不知道怎么解决!

也可能是你的模型在一些地方有比较小的面,而你的interval size相比之下比较大

我这里运行你的jou文件出现的错误是
1 contains 18 highly skewed elements(equisize skew >0.97)

参考http://forum.vibunion.com/forum/viewthread.php?tid=38439
