湍流算例porousBlockage出现错误



  • 东岳老师好,大家好:
    我是正在学习OpenFOAM的新手
    最近在学习模拟湍流时运行pisoFoam下自带算例porousBlockage时出现错误:

    Create time
    Create mesh for time = 0
    Reading field p
    Reading field U
    Reading/calculating face flux field phi
    Selecting incompressible transport model Newtonian
    Selecting turbulence model type laminar
    Selecting laminar stress model Stokes
    No MRF models present
    Creating finite volume options from "constant/fvOptions"
    Selecting finite volume options model type explicitPorositySource
        Source: porosity1
        - selecting cells using cellZone porousBlockage
    --> FOAM FATAL ERROR:
    Cannot find cellZone porousBlockage
    Valid cellZones are 0()
    
        From function void Foam::fv::cellSetOption::setCellSet()
        in file cellSetOption/cellSetOption.C at line 142.
    
    FOAM exiting
    

    请问是什么原因呢?

    此外,还想问一下,如果使用标准k-epsilon模型(RAS算例下)模拟湍流,进出口使用什么条件比较合适呢?
