Hi

I am a relatively new user of OpenFoam, working in the area of combustion dynamics, and needed some help with transient boundary conditions.

The combustion system is divided into 3 components: the inlet channel (non-reacting flow), the combustor (reacting flow computations in this region), and the exhaust (models acoustics using 1D gas dynamics); the three are to be linked by appropriate boundary conditions (ie coupled at the inlet and exit planes of the combustor).

I saw that groovyBC be used for coupling of patches. The sample case for groovyBC defines 3 regions:
Region A: inlet ; interface11
Region B: interface12 ; interface21
Region C: interface22 ; outlet

However, I am interested in performing the reacting simulations only in the combustor region. Could someone please point out how it may be used for the above case, or if there are other ways to implement it?
Any tips would be useful, as I still learning working with OF!

Thanks so much!
