Hello All,

I am simulating a multiphase flow inside an annulus in Fluent. See figure attached (red arrows represents flow direction).

I am able to monitor the volume fraction as function of time inside the whole annular volume. However I would like to monitor it only in the expanded region.

I know it can be done in the Adapt tab and mark cells for a new zone. But, this zone I am creating is totally different from cylinder shape in the expanded region.

What would be the best way to create this volume ?

How it can be done in CFD-Post ?

Thanks in Advance.

Ansys staff do not look into attachment. You can insert your picture. From the description and if you can identify the "zone" by coordinates you might create a Expression Based Report Definition.

Hi abenhadj,

Follow my figure below.

Hi,

This is how you should be able to create an Expression based monitor. But, if I remember right, this might not be possible in 19.2. Could you please check if you are seeing this option?

Thanks.

Kremella,

I am able to see it. But my tab is different from yours.

However, in the left column, from Named Expressions I have it.

 

Thanks.

This might be because of different versions. But, this is what my colleague Amine is referring to.

Thanks.
