计算报错未定义关键词PIMPLE

各位朋友新年好!
最近想在of2.3版本上跑一个空化case,用的LES一方程涡粘模型,以前这个case在6.0版本运行没有问题,但在2.3上报错如下:
--> FOAM FATAL IO ERROR: keyword PIMPLE is undefined in dictionary "/project/ll/new/system/fvSolution" file: /project/ll/new/system/fvSolution from line 20 to line 133. From function dictionary::subDict(const word& keyword) const in file db/dictionary/dictionary.C at line 643. FOAM exiting
自己对照着of2.3的tutorials中的case修改了好久,也不知道哪里出了问题,,,
fvSolution文件如下:solvers { alpha.water { nAlphaCorr 1; nAlphaSubCycles 1; cAlpha 1; MULESCorr yes; nLimiterIter 5; solver smoothSolver; smoother symGaussSeidel; tolerance 1e-8; relTol 0; maxIter 100; } alpha.waterFinal { nAlphaCorr 1; nAlphaSubCycles 1; cAlpha 1; MULESCorr yes; nLimiterIter 5; solver smoothSolver; smoother symGaussSeidel; tolerance 1e-8; relTol 0; maxIter 100; } "U.*" { solver smoothSolver; smoother symGaussSeidel; tolerance 1e-6; relTol 0; }; pcorr { solver PCG; preconditioner { preconditioner GAMG; tolerance 1e-05; relTol 0; cacheAgglomeration true; nCellsInCoarsestLevel 10; nPreSweeps 0; nPostSweeps 2; nFinestSweeps 2; agglomerator faceAreaPair; smoother DICGaussSeidel; mergeLevels 1; } tolerance 1e-05; relTol 0; maxIter 500; } p_rgh { solver GAMG; tolerance 1e-07; relTol 0.00001; smoother DIC; } p_rghFinal { solver PCG; preconditioner { preconditioner GAMG; tolerance 1e-7; relTol 0; nVcycles 2; smoother DICGaussSeidel; nPreSweeps 0; nPostSweeps 2; nFinestSweeps 2; cacheAgglomeration true; nCellsInCoarsestLevel 10; agglomerator faceAreaPair; mergeLevels 1; } tolerance 1e-07; relTol 0; maxIter 1000; } "(U|k)" { solver smoothSolver; smoother GaussSeidel; tolerance 1e-08; relTol 0.1; } } "(U|k)Final" { solver smoothSolver; smoother GaussSeidel; tolerance 1e-08; relTol 0; } } PIMPLE { momentumPredictor no; nCorrectors 2; nNonOrthogonalCorrectors 1; }
哪位朋友可以给我提供点解决思路呢??

是的,已经解决。
解决方法是 直接拷贝一个低版本(我用的2.3版本)tutorials里面case的 fvSolution文件,以这个文件为基础模板,进行相应的修改(即把高版本的代码 对应的替换过来)
我分析我以前犯的错误应该是一些格式性的问题,以后还是不要乱用为好!
最后给大家分享一下,我修改的在of2.3里面可以运行的fvSolution文件代码
