求解过程终止，这个错误怎么回事，BH数据可以吗？
求大家帮助，在求解过程终止弹出的错误是*** WARNING *** CP = 1461.807 TIME= 18:59:11
The B-H curve evaluation algorithm did not converge.Consider adding
more data points at locations having a rapidly changing slope and make
sure the curve does not have reversals in curvature.

这是怎么回事，难道是BH数据不行，下面是BH曲线图和附件BH数据
