I'm struggling with the same problem you did. I tried to used the steps you have provided to develop a new scalarTransportFoam to avoid diffusion of tracer into other phase. No success so far! Is there any chance you share the equations you put in scalarTransportFoam solver?

Thanks and regards,

Hello abbas,

I have the same problem as you had. I would like to know whether you addressed the problem or not.
I have a concentration of sugar in my geometry. I would like to simulate the bubble motion in a solution of water and sugar. The problem is, the sugar concentration penetrates inside the bubble which is not realistics at all. I wonder how I can avoind this problem actually. I would be more than happy if you halep me to address the problem.

Best,
Sadra

Hey voingiappone

It would be great if you could upload the code you used to fix this problem :)

Thank you!

Hi kuria,

I have the same problem. Could you address the problem finally?
I have a bubbly flow in a solution of water and sugar. The sugar also penetrates inside the bubble which is not true and I would like to avoind it but I have no idea what to do.

Best,
Sadra
