CFX沸腾求助

我正在使用CFX-12做有关液氮沸腾的模拟，现在出现了一个问题
在solver中反复出现：
cal_TSUP1 WARNING

Wall superheat bisection algorithm

failed to converge.

Continue with wall superheat = 1.0000072E-01

of minimum relative error = 4.5705986E-01


最后的结果出现：

| ERROR #001100279 has occurred in subroutine ErrAction. |

| Message: |

| Heat partitioning algorithm failed to fix upper bound of bisecti- |
| on

只要我一激活wall boiling model的RPI model 把进口条件改为速度0.3m/s，就会出现上述的错误
那位高手能帮我解答一下，不胜感激

fluent里面有一个直径boiling example.
