求解水蒸气两相流时遇到的问题，望高人指点迷津！

xul

我在计算时的问题为：求解某汽轮机的末级其工况为静叶进口总压为31171pa，总温为343.45K，动叶出口背压为5860Pa。工质选的为Redlich Kwong的H2ORKvl，静动叶交界面设为stage，收敛步长为0.0001S。
1、以上设置如果把工质选为理想气体，算得结果可以收敛。说明网格没有问题。
2、直接设置背压为5860Pa，算上几步就说静压在动叶处溢出而算不下去。
                        ****** Notice ****** |
| While evaluating H2ORKv.Saturation Enthalpy, |
| Static Pressure on interface rotor |
| went outside of its lower limit. Its minimum value was |
| -3.5605E+02. The bounds error was handled by clipping. |
| If this situation persists, consider increasing the table range. |
+--------------------------------------------------------------------+
3、把出口设置为超音速，计算可以收敛，但计算出来的结果与实验结果相差太大。
4、把背压设置为15000Pa，算了500步，CFX——Slover manager面板下p、u 、 v、w的线最后变量值在0.0001以下达到水平（至少有300步）。可以认为它已达到收敛。但是在关闭它的时候，出现提示说在150步的时候牛顿跌代发散。接着把背压设置为10000Pa时，算了200步结果CFX——Slover manager面板下p、u 、 v、w的线最后变量值在0.0001以下达到水平（至少100步），最后关闭它的时候，还是提示它在150步时出现牛顿跌代发散。
              ****** Notice ****** |
| Newtons method failed to converge in 150 iterations. This |
| occured while computing the following variable: |
| |
| Variable Name : Static Pressure |
| Location Name : rotor |
| Mesh location : VERTICES |
| Mesh entity : |
| Last 3 Changes : 1.08472E+03 1.08469E+03 1.08466E+03 |
| Tolerance : 1.0000E+00 |
| |
| The Newton iteration was either slowly converging or has stalled. |
| The solver will continue with the variable set as it was on the |
| final iteration. If this situation continues you might try |
| increasing the number of iterations allowed for Newtons method. |
| This can be changed by setting one of the parameters: |
| |
| Temperature : "Constitutive Relation Iteration Limit" |
| Pressure : "Newton Pressure Iteration Limit" |
| |
| for your mixture using the definition file editor. |
+--------------------------------------------------------------------+
5、把背压设置为5860Pa，利用4步骤中得到的结果插值，同样出现说静压溢出。
请问哪位高人怎么解决这个问题！

xul

此问题继续：
    这几天我算了一个背压8000Pa的最后能基本上收敛，通过设置专家参数中的slove relaxation scalar =0.75 和 slover target reduction fluids =0.75 解决了最后的牛顿跌代发散问题。但是关闭求解器的时候，出现了两个结果文件。一个正常的xx.res一个xx.res.err，第一个文件的后处理中需要的变量都存在。计算中间没有提示出现错误，但是在关闭的out文件最后说的还是动叶处静压超出范围，但是Redlich Kwong的水蒸汽的压力范围应该在物理上包含我计算的压力范围。
     接着我用8000pa的res文件进行插值计算背压5860pa，在计算到26步时提示

End of solution stage.

| Warning! |
| |
| The CFX-5 Solver has written a crash recovery file. This file has |
| been saved as d:\vic\cfx\coarb4_001.res.err and may be an aid to |
| diagnosing the problem or restarting the run. More details should |
| be available in the solver output section of the output file. |
| Note that a lock file was left for the crash file when the solver |
| exited, and so it is probably incomplete. |

同样写了两个结果文件xx.res和xx.res.err，但是这次res文件中没有得到需要求解的物理量（p，T，U，v，w等），只是一些几何变量。
      
   为了求解这个问题折腾了好久了，先是调网格，网格在Icem中做的，动静叶流道的网格都是结构化的，最后网格检查没有出现错误，网格质量都在0.4以上。
     后来调背压，就如以上所说的那样操作。
   
有没有哪位同仁同样遇到过这样的问题，请加以指点迷津！
