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
