求助UDF并行计算的问题

各位大佬，求帮忙看一下计算出错的原因。
我模拟一个结晶的过程，在PBE模型中挂上成核与生长的UDF时，计算一开始就出现了报错，不挂UDF就可以正常计算下去。报错时控制台的提示信息如下：Initialize using the hybrid initialization method. Checking case topology...

应该是UDF的问题，但不知道具体是什么问题。生长速率udf代码如下：

你的是并行计算挂载有问题，串行计算没有问题吗？

看提示信息说的是浮点数溢出，没遇到过这种错误，期待UDF大佬现身说法

你检查一下UDF里的参数

@关伯兰在笑 逐行排查吧，所有分母都添加一个很小的量。
