hello everyone
I have simulated fluid flow in a pipe. velocity inlet was defined at the inlet of the pipe . I want to set the velocity profile the same as which has been shown in the picture. this function does not have an specific definition so I think I have to define it by list of digits which is consist of velocities and times.
I have no idea about defining these digits as a velocity inlet in Openfoam, please help me to solve the problem.
thanks

should I define it in this way?

OpenFOAM table file
uniformValue     tableFile; 
tableFileCoeffs 
{ 
    fileName     "$FOAM_CASE/myDataFile" 
    outOfBounds  clamp; 
}
