Hello, I am new to FLUENT and I am trying to simulate a water coning behaviour in an oil reservoir using the VOF method.

My model is a huge cylinder (porous zone), partially filled with water and partially with oil (50/50). In the centre of this cylinder there is a small hole (much smaller radius) representing the well.

To maintan pressure (210bars) at the outer boundary of this huge cylinder (reservoir), the same amount is being injected at the sides (mantle) which is being produced from the well (5000 bbl/day). Top and Base of the cylinder are considered to be walls.

What would you suggest: Which boundary conditions should I specify for the sides of the reservoir (inlet) and which for the well (outlet), because I could not find any boundary condition with a volume ouflow rate.

Thanks.
