I am trying to set up an iMUSIG polydispersed model in CFX. I want to have 2 velocity groups with 12 size groups in each. I define water as the continuous phase and air1 &air2 as polydispersed phases. For air1 I set the diameter range 0-6mm, air2 has 6-12mm size groups.
Does CFX automatically couple the two velocity groups, as in coalescence of velocity group 1 into velocity group 2. If not, how do I set it up?
When I run my current setup as described it solves fine but I am getting 90% size fraction in the largest bubble size of velocity group 1 and essentially no mass moving into velocity group 2.December 7, 2020 at 6:27 pmSurya DebAnsys EmployeeHello,
Did you setup the Breakup and Coalescence models in the Polydispersed Fluids tab?
You can get more information from the link below.

I think I found my problem. I was using 19.2 version and there was only MUSIG in the drop down menu. I switched to 20.1 and now there is an option for iMUSIG.
Thank you for the help.
