结果出现下边的警告
*** WARNING ***                         CP =    5243.750   TIME= 14:16:24
A reference heat flow value times the tolerance is used by the         
Newton-Raphson method for checking convergence.  The calculated         
reference HT FLOW CONVERGENCE VALUE= 0 is less than a threshold.  This  
threshold defaults to 1.0e-6 or is specified as MINREF on the CNVTOL   
command.  Check results carefully.        

求大神帮帮忙,该怎么解决呢,为什么会有HT的呢
