blockMesh 执行出错：lambda=1

[李子橙]

大家好，我在执行 blockMesh 时出现了如下错误

Create time

Creating block mesh from
    "system/blockMeshDict"
Creating block edges
No non-planar block faces defined
Creating topology blocks


--> FOAM FATAL ERROR: 
Parameter out of range, lambda = 1

    From function virtual Foam::point Foam::blockEdges::lineEdge::position(Foam::scalar) const
    in file blockEdges/lineEdge/lineEdge.C at line 79.

FOAM aborting

这个问题已经在我这儿搁置了半个月了，仍未有任何解决办法，下边是出错的 blockMeshDict 文件，针对此问题，请教一下各位老师是否有解决的思路。谢谢！
