Hi,

I have a multi-domain problem run in transient, and I want to find out the mass of a specific fluid that exists in a particular domain. What is the formula to do this in cfx post? It doesn't seem to like mass('fluid')@domain

I think this is an easy problem but I haven't found out how to do it yet. Thanks, Tim.

Hi

The easiest way is using Function Calculator in CFX post i.e.using the option of mass flow and specify the 2D region in function calculator, you can get the mass flow at particular 2 D region

I am able to find the mass flow for a 2D region, but I am actually after the mass of a fluid in a 3D domain.
