Dear Foamers,
Please any help or advice to push my geometry out. I am using OF2.1.1 . I have Injector inside combustion chamber, I have inlet fuel(patch), inlet air(patch) out let(patch in the bottom) and the rest is walls including the internal ones for the injector as in the you can see in the attached sketched. I used topoSet dict to define the injector walls and createBaffles utility but it did not work. What to do? any thoughts? below is my blockmesh dictionary and toposet file as well.
