边界条件tableFile读取错误问题

Hope

模拟二维大气边界层流动，入口添加ESDU的对数律剖面时，采用如下方式定义，

INLET
   {
       type            fixedProfile;
   profile 	tableFile;

   profileCoeffs
   {
           nHeaderLine         0;          // Number of header lines
           refColumn           1;          // Reference column index
           componentColumns    (1);    // Component column indices
           separator           " ";        // Optional (defaults to ",")
           mergeSeparators     no;         // Merge multiple separators
           file                "inVelocity.txt";//"inletProfiles/inVelocity.csv";
           outOfBounds         clamp;      // Optional out-of-bounds handling
           interpolationScheme linear;     // Optional interpolation scheme
       }
       direction        (0 1 0);
       origin           0;
    }

运行simpleFoam时，提示如下错误

inVelocity.txt文件为

不知道问题在哪里？还请各位指教

速度应该给矢量？你这是标量

Hope

@东岳李老师，我边界条件代码修改后如下：

    INLET
    {
        type            fixedProfile;
	profile 	tableFile;

	profileCoeffs
	{
            nHeaderLine         0;          // Number of header lines
            refColumn           0;          // Reference column index
            componentColumns    (1 2 3);    // Component column indices
            separator           ",";        // Optional (defaults to ",")
            mergeSeparators     no;         // Merge multiple separators
            file                "inVelocity.txt";//"inletProfiles/inVelocity.csv";
            outOfBounds         clamp;      // Optional out-of-bounds handling
            interpolationScheme linear;     // Optional interpolation scheme
        }
        direction        (0 1 0);
        origin           0;
     }

同时inVelocity.txt数据按照下面格式给出，但还是有同样的报错信息

3.07832,0,0

文件位置正确么？

Hope

@东岳嗯嗯，是在同一个文件夹0/下的

        direction        (0 1 0);
        origin           0;
    }

inVelocity

(
            (0.0 (1 2 3))
            (1.0 (4 5 6))
)

另外写在csvFile更容易些：

inlet
    {
        type            fixedProfile;
	profile 	   csvFile;
...
      }

Hope

@东岳好的，我试一下。谢谢老师~
