求助：ANSYS仿真遇到收敛问题

alice_blue

如题。
*** WARNING ***                         CP =      60.560   TIME= 09:56:08
The calculated reference HT FLOW CONVERGENCE VALUE= 1.623682755E-11 is  
less than the default minimum of 1E-6 (which can be modified using the  
MINREF field of the CNVTOL command).  Check results carefully.  

求助各位这个问题该如何解决？网上查有说是“这个应该属于warning范畴，在你的计算中，并没有热的传导产生，从而无从谈起计算的收敛。你一定是在热的加载过程中出了问题。”
可是不知道该如何解决啊，好几天了还是不知道如何解啊
