Dear friends,
I have to add temperature equation to icoFoam solver with and without source terms to be solved conditionally in different regions, i.e.:

for region 1
{
energy equation + source_term =0;
}

for region 2
{
energy equation =0;
}

I know at which line I have to add these equations. I have done it successfully. The only issue is to write the conditions for region 1 and region 2. I don't know how to make openFoam understand x, y and z coordinate in the solver itself so that it can solve it conditionally.


It will be a great help if you guys look into the matter.

Thanks
