<![CDATA[对于openfoam旋转坐标系边界条件设置的疑问]]>大家好，最近在阅读openFoam 4.1版本tutorials/incompressible/SRFSimpleFoam/mixer 算例，在读到设定边界条件的0/Urel文件时有个地方一直百思不得其解...附上Urel文件的代码:

/*--------------------------------*- C++ -*----------------------------------*\

FoamFile
{
    version     2.0;
    format      ascii;
    class       volVectorField;
    location    "0";
    object      Urel;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions      [0 1 -1 0 0 0 0];

internalField   uniform (0 0 -10);

boundaryField
{
    inlet
    {
        type            SRFVelocity;
        inletValue      uniform (0 0 -10);
        relative        no;
        value           uniform (0 0 0);
    }
    outlet
    {
        type            pressureInletOutletVelocity;
        value           $internalField;
    }
    innerWall
    {
        type            noSlip;
    }
    outerWall
    {
        type            SRFVelocity;
        inletValue      uniform (0 0 0);
        relative        no;
        value           uniform (0 0 0);
    }
    cyclic_half0
    {
        type            cyclic;
    }
    cyclic_half1
    {
        type            cyclic;
    }
}


// ************************************************************************* //

中的这几行:

 inlet
    {
        type            SRFVelocity;
        inletValue      uniform (0 0 -10);
        relative        no;
        value           uniform (0 0 0);
    }

对于进口速度，已经设置了其速度为 uniform (0,0,-10)，那为什么下面还需要写一行 value uniform (0,0,0)?这一项代码有什么含义？想不通:joking:
