WebMay 5, 2024 · Here you are trying to activate automatic mesh refinement, which helps fluent to refine/coarsen the mesh during a calculation. What I suggested is to try refining the mesh before you import it in Fluent solver. In simple words, try reducing the size of the cells in your mesh. Note that, this will increase the overall computational time. Nikhil WebOct 12, 2005 · I did try 2nd order upwind scheme for pressure and QUICK for momentum but continuity didn't converge (10^-2). I also tried using density based solver but that didn't work either. I am simulating a pipe flow using a nist-real-gas-models with gravity and buoyancy effects. my BC's are mass flow inlet, pressure outlet and const wall heat flux.

WebMar 14, 2016 · It depends on the initial guess, on the parameter you check, on the geometry of the domain, and so on, how much your residuals will need to drop before you can say the solution is converged. So, based on the residuals alone, you can never say your simulation has converged. You will need to check something else.
