Hello
I need varying BC for interstitialInletVelocity which can be found in DPMFoam/Goldschemidt. Using table for fixed value:

    
bottom
{
    type uniformFixedValue;
    uniformValue table
    (
        (0 (0 0 1))
        (0.001 (0 0 2))
        (0.002 (0 0 3))
        (0.003 (0 0 4))
    );
    }

the run starts without error. But for interstitialInletVelocity"
The default is:

    bottom
    {
        type            interstitialInletVelocity;
        inletVelocity   uniform (0 0 1);
        value           uniform (0 0 1);
        phi             phi.air;
        alpha           alpha.air;
    }

trying to time varying it by:

    bottomSB
    {
        type            interstitialInletVelocity;
        inletVelocity   uniformFixedValue;
    uniformValue table
(
        (0 (0 0 1))
        (0.001 (0 0 2))
        (0.002 (0 0 3))
        (0.003 (0 0 4))
);

        value           table
(
        (0 (0 0 1))
        (0.001 (0 0 2))
        (0.002 (0 0 3))
        (0.003 (0 0 4))
); 
        phi             phi.air;
        alpha           alpha.air;
    }

gives this error:

--> FOAM FATAL IO ERROR: 
expected keyword 'uniform' or 'nonuniform', found table

Change of second "table" to "nonuniform" also gives error:

I checked other changes by "Banana" trick debugging but it doesn't work. This boundary condition is suitable for two phase flows because It consider the inlet porosity so we will sure about fixed value of inlet flow rate. It is not possible to use simple fixed value BC and should use interstitialInletVelocity instead. If anyone know about time varying this BC please share here.
Best,
