Class
Foam::tabulatedWallFunctions::general
Description
Computes U+ as a function of Reynolds number by inverting table of
y+ vs U+
Example dictionary specification:
tabulatedWallFunction general;
// Output table info
tableName uPlusWallFunctionData; // Output table name
log10 yes; // Re interpreted as log10(Rey)
dx 0.2; // Interval log10(Rey)
x0 -3; // Minimum log10(Rey)
xMax 7; // Maximum log10(Rey)
generalCoeffs
{
interpType linear; // Interpolation method
log10YPlus true; // y+ values defined as log10(y+)
log10UPlus true; // U+ values defined as log10(y+)
inputTable
(
(yPlusValue0 uPlusValue0)
...
(yPlusValueN uPlusValueN)
);
}
