I'm trying to simulate a bubble rising process using interFoam with a time-dependent boundary condition in the inlet, but I get the following error.

--> FOAM FATAL IO ERROR:
keyword file is undefined in dictionary "/home/chir/OpenFOAM/chri-9/0.0715mm_test/0/U.boundaryField.inlets"

file: /home/chir/OpenFOAM/chri-9/0.0715mm_test/0/U.boundaryField.inlets from line 50 to line 54.

Hello


You probably used the wrong keyword. OpenFoam expects a file keyword and your 0/U file only has tablefileCoeffs in your inlets boundary.

I try to modify the boundary condition of inlets，It works！

inlets
{
type uniformFixedValue;
uniformValue tableFile;
uniformValueCoeffs
{
file "velocity.txt";
}
value (0 0 0);
}
my velocity.txt is ：
