Hi.
I need to increase the wall temperature by 10K for each iteration.For example, the wall temperature in the initial time is 400 K, after 0.5 it is 1000K. Unfortunately, I do not know how to do this. Please help me.
Code:
dimensions      [0 0 0 1 0 0 0];

internalField   uniform 400;

boundaryField
{
    top
    {
        type            zeroGradient;
    }

    bottom
    {
        type            zeroGradient;
    }

    walls
    {
        type            fixedValue;
        value           uniform 400;// how to increase it for each iteration
    }

    symmetry
    {
        type            symmetryPlane;
    }

    frontAndBack
    {
        type            empty;
    }
}

Thank you. I tried to use it, but it did not help me. How to use uniformValue for temperature?
