大家好，请教一个ansys热源加载的问题！

大家好，想请教一个问题，我这个是用ansys的函数加载功能加载体热源，但是在求解时就会报错：
*** ERROR ***  The L-2 norm of the residual force overflowed.  This may be caused by    PRED,ON or birth/dead elements.  Please use PRED,OFF and try again.不知道什么原因，希望大家给我宝贵的意见，谢谢啦！具体的命令流如下：

大家对命令流有什么看法，麻烦给点意见，谢谢！

choudoufu99

问题可能出在加载函数的过程中  建议 在加载函数时用界面操作 然后再把这部分命令流全部复制出来

谢谢你的帮忙，我这个就是先用GUI方法试验的，但是就是加载求解就出warning！不知道怎么回事！
