Hi Foamers,

i was working in tutorial of solver chtMultiRegionFoam case of multiRegionHeater.

in system/bottomAir directory there is a file named "change Dictionary dict" within it change of boundaries but there is some thing i don't understand:

what ".*" means and what "bottom_to_.*" means in t

T
{
internalField uniform 300;

boundaryField
{
".*"
{
type zeroGradient;
}

"fluid_to_.*"
{
type compressible::turbulentTemperatureCoupledBaffleMix ed;
neighbourFieldName T;
K basicThermo;
KName none;
value uniform 300;
}
}
}

thanks in advance.
