Hello Everyone,


I generated a heat source using fvOptions. but I have a confusion in this. Below attached is my fvOptions file:

heatSource
{
    type            scalarSemiImplicitSource;
    active          true;
 
    scalarSemiImplicitSourceCoeffs
    {
        selectionMode   all; // all, cellSet, cellZone, points
       // cellZone        heatSrc;
        cellSet         c1;
        volumeMode      specific; // specific;
        injectionRateSuSp
        {
            h     (100 0);
        }
    }
}

If I change the value of h, the value of temperature in my geometry changes, but some different value, for example, if change the value of h from 100 to 1000, the temperature changes from 304K to 340K.



what is 'h' in this file that we are changing? Is it Power? Enthalpy? or something else?


And according to which equation, the values of temperature are changing?



And my log file is given below:

 Adding fvOptions

Creating finite volume options from "constant/fvOptions"

Selecting finite volume options model type scalarSemiImplicitSource
    Source: heatSource
    - selecting all cells
    - selected 767 cell(s) with volume 1

What is volume 1 in this? because I was expecting that the value of 'h' here. but I don't understand what's happening here.




I want a heat source, in which I can change the power and get the temperature changing as a result.


Any help would be highly appreciated.


Thank you
