Problem in convergence for simulate wind flow around building
Hi,
i am mech undergrad, currently i am doing my simulation of air flow around building for my final year project. I am using FLUENT 6.2.16 with standard k-e model. But my simulation is unable to converge to meet the converge criteria until 1800 iterations. It keep on pop out the message of reverse flow at my outlet. I tried with a bigger computational domain and yet i am still unable to get the solution converge. Is there anything i can do in order to get the solution converge? Thanks. Best regards. |
try this
Hi,
there are many things you can do First, I do not know how you changed the domain... you do not need larger domain but need to extend it (of course other boundaries must be may be P inlets). The other thing is: may be you use low speed of wind, so.... it is possible to have so called "unsteady-steady" state... so try to use unsteady solver. |
i make it bigger like i extend the top, lateral and downstream domain.
My inlet is the logarithmic velocity inlet while my downstream outlet is pressure outlet. The top and lateral boundaries was symmetry. I tried with unsteady solver but the solution just cant converge to what i want. |
