CFD Online Discussion Forums - Set a phase shift to the sinusoidal veolocity

Hello,

I am using OpenFOAM version 6 and chtmultiregionfoam solver. This is my current boundary condition (sinusoidal motion) for the velocity of water region (fluid region):

Code:

internalField   uniform (0 0 0);



boundaryField

{

    #includeEtc "caseDicts/setConstraintTypes"



    minX

    {    

        type        uniformFixedValue;

    uniformValue sine;

        uniformValueCoeffs

        {

            frequency 0.1;

            amplitude 0.015;

            scale     (0.8 0 0); 

            level     (0 0 0); // offset

            t0          0; // shift this for a Cosinus

        }          



    }

    maxX

    {

        type            zeroGradient;

    }



    "(min|max)(Z)"

    {

        type            empty;

        ~value;

    }



    "water_to_.*"

    {

        type            noSlip;

    }

}

If I want to give a phase shift of the sinusoidal waveform (for instance, a 60 degree shift), how can I impose it? (I guess I would have to modify the t0 value but I am not sure how precisely).

Thank you all for your help!
