i am a new user in Fluent.
i want to know what exactly is meant by operating pressure in fluent?
its default value is 101325 pa, is it atmospheric pressure? but sometime we also assume 0 as operating pressure, its making me feel dizzy....
what will be the operating pressure in 10 meter depth of a pool?

It depends on how you model the density. It is always valid to set the operating pressure to (approximately) the mean pressure of the flow field. But it is only when you model the density using incompressible ideal gas law, or you are dealing with low-Mach-number compressible flow that the value of operating pressure is important.
The operating pressure is not used if the density is modeled to be constant.
You should check the Fluent user manual because it has more detailed and accurate description of the operating pressure.
