Hi Sir,nI am simulating a free convection problem. So, I don't know which solver(pressure-based or density-based) should I take here?nMy senior suggest me to go with a density-based solver because in natural convection density varies.nI hope you understood my question. TIAnnThank you,nAbubakar khan n

I'd use the pressure based solver as the fluid is unlikely to be moving in excess of Mach 3. However, I would use a variable density material and make sure gravity was defined. n

[Abubakar]

Thank you sir for your response. I have a follow-up question. What do you mean by variable density material? TIAnnThank you, nAbubakar Khann

Open the materials panel and look at the options for Density. They're explained in detail in the documentation. n

Ok sir will do that thanks for response. n
