I am trying to adjust dnsFoam
 
I am trying to adjust dnsFoam to calculate the decay of turbulence (in space). For that, in my domain (say 32, 16, 16 - with inlet bc) the turbulence forcing is active in the first half only (1:16,1:16,1:16), the other part should be calculated without the extra source term. How can I do that in a compact and elegant way? Some CFD codes allow to define different fluid zones, is that a case with OF? I've got no experience with OF and need some help

Regards,
Mick
