Hello all,

I am using reactingFoam with OF 2.2.0 to simulate turbulent premixed combustion. Attached here is my mesh for the computational domain.

I wanted to ignite the flame which is why I have decided to use setFields for flame ignition. Following is the file I picked up online.

regions
(
    boxToCell
    {
        box (-1 -1 -1) (1 0 1);
        fieldValues
        (
            volScalarFieldValue T 1650
        );
    }
);

1. Can this same file be used for OF 2.2.0??
2. What does the term boxToCell mean and are the points (-1 -1 -1) and (1 0 1) the corner points of the box??
3. If I have a 2D axisymmetric mesh as shown in the link above, how can I specify a region/plane of high temperature??
3. If I want to give the information that the premixed gas, CH4+O2 is fully burnt in this box, how can I do so ??
