how to improve convergence for fine mesh E-E model for fluidized bed?
the convergence is 1e-8s! and takes ages (literally) :( to get 0.1s of simulation- its a solid bed with freeboard above and gas velocity inflow bc at bottom.
even 1e-7,1e-6s time step would make a huge difference. any tips?? |
How many phases are there in your simulation? what is the number of transport equation which should being solved and the degree of coupling? hence, you should enter 1e-3 for absolute criteria of continuity, and enter 1e-5 for time step at first simulation, before this procedure you must simplify your problem.

hi i am simulating a fluidized bed. i have a problem. there is reversed flow at outlet boundary and the solution does not converge. how can i solve this problem. Thank you in advance |
be sure the gravity is activated

i activated gravity in general setting should i active gravity in operating condition? |

yes it must be activated in operating condition panel

Hello All,
I want to do analysis of heat transfer from water flowing through pipes submerged inside concrete. I am modelling in GAMBIT and wish to analyse it on Ansys FLUENT. Can anybody help me out, how to model and simulate? Does any tutorials exist? |
