August 4, 2013, 02:50	Which boundary condition for zero gradient	#1
Rojj Member Ruggiero Guida Join Date: Apr 2013 Location: World Posts: 46 Rep Power: 12	Dear group, I am modelling a shopping mall gallery. This is simply a long, two storeys corridor. It's entire length is 150m and it has an approximate width of 20m. I am modelling only a section that is 40m long. The boundary conditions I am planning to use for the two 'cuts' are zero-gradient. The idea is that the immediate cells next to the boundary have the same value of the adjacent cell inside the domain. How do I model this condition in Ansys Fluent. Is it correct in your opinion? Thanks for any advice.
