Results control: Why isn't possible to add a scalar transport in multiphase analysis?

Using SimScale
1

I would like to use a transport scalar in a multiphase simulation. Normally it is available in results control. However when I select multiphase analysis the item transport scalar disappears from results control options. So, how could I use a scalar transport in a multiphase simulation?

Hi @lineker!

Getting back to you soon, will check that out!

Edit: As far as I know there has never been an option like this for multiphase, correct me if I am wrong. Do you have a project example?

Best,

Hi Jousef,
For example: The Water Separation project I did in SimScale. It is a water free surface simulation based on multiphase analysis in which I want to use a scalar to determine concentration decay in the tank to obtain Hydraulic Detention Time (HDT) of a tracer (scalar).

Hi @lineker!

In your project you can see that this result control item is only available for incompressible flows. The Multiphase Flow module does not allow this type of item. You might add your query in the Vote For Features section.

Hope that clears things up a bit. All the best!
