I had created the velocity from 1 knot to 12 knot (so it will write the folder of parameter form t=0 to t=11) by type timeVaryingMappedFixedValue;
but it gives me an error message

inlet
{
    type            timeVaryingMappedFixedValue;
    value           uniform (0 0 0);  // Default velocity value (optional)
    table           
    (
            (0.0 (-0.514444 0 0))   // At time = 0, velocity is -1 knot (-0.514444 m/s)
    (1.0 (-1.028888 0 0))   // At time = 1, velocity is -2 knots (-1.028888 m/s)
    (2.0 (-1.543333 0 0))   // At time = 2, velocity is -3 knots (-1.543333 m/s)
    (3.0 (-2.057777 0 0))   // At time = 3, velocity is -4 knots (-2.057777 m/s)
    (4.0 (-2.572222 0 0))   // At time = 4, velocity is -5 knots (-2.572222 m/s)
    (5.0 (-3.086666 0 0))   // At time = 5, velocity is -6 knots (-3.086666 m/s)
    (6.0 (-3.601111 0 0))   // At time = 6, velocity is -7 knots (-3.601111 m/s)
    (7.0 (-4.115555 0 0))   // At time = 7, velocity is -8 knots (-4.115555 m/s)
    (8.0 (-4.630000 0 0))   // At time = 8, velocity is -9 knots (-4.630000 m/s)
    (9.0 (-5.144444 0 0))   // At time = 9, velocity is -10 knots (-5.144444 m/s)
    (10.0 (-5.658888 0 0))  // At time = 10, velocity is -11 knots (-5.658888 m/s)
    (11.0 (-6.173333 0 0))  // At time = 11, velocity is -12 knots (-6.173333 m/s)
    (12.0 (-6.687777 0 0))  // At time = 12, velocity is -13 knots (-6.687777 m/s)
    (13.0 (-7.202222 0 0))  // At time = 13, velocity is -14 knots (-7.202222 m/s)
    (14.0 (-7.716666 0 0))  // At time = 14, velocity is -15 knots (-7.716666 m/s)
    );
}

you are using the wrong BC type


use fixedValue or uniformFixedValue and supply the table


timeVaryingMappedFixedValue "Maps" data from a table onto a patch, in space and space&time. Since you are not mapping onto a patch, it is the wrong BC.

Pardon, I have already rewrited the type of BC. but i'm just doubt for the outlet BC, because, it set into outletPhaseMeanVelocity, but unfortunately, i don't know how to set the scalar of "Umean"?

Example

If the interval time write at t=1, U value= (-0.514 0 0) at inlet and Umean and U value are 0.514 and (-0.514 0 0 0).
If the interval time write at t=2, U value= (-1.028 0 0) at inlet and Umean and U value are 1.028 and (-1.028 0 0 0).
And so on

Sorry for confused interpretation
