question of "uFluctTemporal" in Tlnf

[zpcfox]

 Dear professors,I do not know about the function of uFluctTemporal in the boundary "in".Can you give me some explanations?Thanks a lot.
in
    {
        type            turbulentDFMInlet;
        value           uniform (7 0 0);
        uFluctTemporal  uniform (0 0 0);
        U               uniform 7;
        R               uniform (70 0 0 70 0 70);
        L               uniform (0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3);
        filterFactor    4;
        filterType      gaussian;
    }

Can I have a look at the UI of TInF where you input this type of inflow condition using digital filtering? I need to check how "uFluctTemporal" is generated. Basically all the information has been included in U, R and L.
