情况是这样:我在用ansys 16.0 transient blade row模型的time transformation模拟一级非定常涡轮叶栅,每个时间步的coefficient loop iteration 1下面总会出现 如下提示:
+--------------------------------------------------------------------+
| ****** Notice ****** |
| The non-dimensional near wall temperature (T+) has been clipped |
| for calculation of Wall Heat Transfer Coefficient. |
| |
| Boundary Condition : S_R Side 2 |
| T+ clip value = 1.0000E-10 |
| |
| 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 functions. You can do so by specifying a Mach |
| number threshold as follows: |
| |
| EXPERT PARAMETERS: |
| highspeed wf mach threshold = 0.1 # default=0.0 (off) |
| END |
+--------------------------------------------------------------------+
请教各位大神:这是什么情况啊?这个叫highspeed wf mach threshold的专家参数我在solver manager的设置里一直未找到,不知道该怎么处理。
另外:我之前用ansys14.5的普通transient非定常模型计算一级涡轮叶栅,也出现类似的提示,同时监测点的曲线一直很难收敛,用13.0计算就没有这个提示,想请教下各位大神,我这个是什么情况?拜谢拉~
