Hi!

I have a question concerning how to update a volScalarField. Imagine the following problem:

You have a volScalarField T for the temperature (with values applied to it). You now have another volScalarField X which is meant to consist of values depending on the respective temperatures. How do I implement an update for X which looks up the temperature of each element and then updates the value in terms of special conditions. With that I mean a procedure of this sort:

if (T<100)
{
    X = 1;
}

if (T=100)
{
    X = 2;
}

if (T>100)
{
    X = 3;
}
