Deffine of different operating pressure

msdkhl · January 12, 2016, 12:20

Hello
i am working on a fluidized bed modeling with ansys fluent..
my case has two phase, 2D and two part..
in fact my bed is a vertical rectangular that verticaly separated in two parts..
i want to deffine different operating pressure at two separate part of bed..
but i cant do it..
Does anybody know what am I doing?

I don't think this is possible. If you want ultra-high precision calculations, then you really should be using two separate but coupled simulations that would each have their own operating pressure.

The philosophy of using an operating pressure is to limit truncation errors. If your average pressures are significantly different in two regions of your domain then truncation errors would not be that significant.
