问题求助！contour integral objects contains regions that cannot be mappe...
各位前辈，我在模拟一个三维环切圆柱，assign seam后生成Crack-1，采用contour integral 计算SIF等断裂参数。singularity设置0.25，collapsed element side, single node.
由于是环切，crack tip是闭合的圆，crack front 是以改闭合圆为轴的圆环。
对crack front采用一圈楔形网格二次单元C3D15R，对剩余contour采用六圈六面体网格二次单元C3D20R，crack front 和contour网格如下图：
但是提交后提示：
The following contour integral objects contains regions that cannot be mapped into layers of node sets.
Review the relevant regions or the underlying mesh. Crack-1
These objects will not be gengerated in the analysis model.
这个问题也没太看明白，也不知道看什么资料寻求解决办法。
请前辈指点迷津。
