本人计算某离心甩油燃烧室，总是出错。模型为1/18，但结构并非完全对称。试过过多次，以前师兄曾经算过，我 用他的网格，自己设置发现可以计算，所以很可能是网格问题，网格质量0.16以上，但又不知问题出在哪里？错误如下： 一种错误： +--------------------------------------------------------------------+ | | | Solver | | | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | | | ANSYS CFX Solver 13.0 | | | | Version 2010.10.01-23.02 Sat Oct 2 02:31:59 GMTDT 2010 | | | | Executable Attributes | | | | single-int32-64bit-novc8-noifort-novc6-optimised-supfort-noprof-nos| | | | Copyright 2010 ANSYS Inc. | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | Job Information | +--------------------------------------------------------------------+ Run mode: serial run Host computer: WIN-T63IF9IQR2K (PID:2172) Job started: Tue Mar 18 09:53:39 2014 +--------------------------------------------------------------------+ | ****** Notice ****** | | | | The specified value for the REAL parameter | | | | SOLVER_RELAXATION_SCALAR | | | | is out of bounds and has been clipped to its UPPER bound. | | | | Lower bound: 1.000E-30 | | Upper bound: 1.000E+00 | | Specified value: 1.200E+00 | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | Memory Allocated for Run (Actual usage may be less) | +--------------------------------------------------------------------+ Data Type Kwords Words/Node Words/Elem Kbytes Bytes/Node Real 92875.7 539.85 106.61 362795.7 2159.41 Integer 28919.2 168.10 33.19 112965.5 672.39 Character 3686.8 21.43 4.23 3600.4 21.43 Logical 80.0 0.47 0.09 312.5 1.86 Double 608.0 3.53 0.70 4750.0 28.27 +--------------------------------------------------------------------+ | ****** Notice ****** | | | | The specified value for the REAL parameter | | | | SOLVER_RELAXATION_SCALAR | | | | is out of bounds and has been clipped to its UPPER bound. | | | | Lower bound: 1.000E-30 | | Upper bound: 1.000E+00 | | Specified value: 1.200E+00 | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | ****** Notice ****** | | The Wall Heat Transfer Coefficient written to the results file for | | Gas Mixture | | is based on the turbulent wall function coefficient.
