Hi, bros:

I want to use DPM model to simulate the gas bubbles, but its density will changes depend on the pressure as well as its diameter. So How can I change it, I cannot found a Macros to do, does anybody have a better idear, Thank you.

You should model it using eulerian approach

Thank you, msaeedsadeghi:
You mean using Miture Model? But I tried many times, it is very hard to converge after few iters. I think there was some error I can not mention. Do you know any place that I have to notice?
