[交流] CFX计算报错,关于T+ clip value value

用CFX模拟超声速圆柱绕流时(湍流模型SST),报错:the non-dimensional near wall temperature (T+) has been clipped for calculation of wall heat transfer coefficient。请问是什么原因导致的?改如何处理呢?(用定常算没问题,算完定常用非定常算,算几步就出错了)。

还有提示:If this situation persists and you are using the high speed model,consider enabling mach number based blending between low speed and high speed wall functons. You can do so by specifying a mach number threshold as follows: EXPERT PARAMETERS: highspeed wf mach threshold = 0.1 #default=0.0(off)。
可是在EXPERT PARAMETERS中找不到highspeed wf mach threshold选项啊?
