Hello,
I have came across one initialization issue in Fluent. My problem is explained as following: I am running one simple 2D transient case. At first i initialized the domain from inlet and solved for five time steps. Solution was converged at each time step. At the end of five time steps i got one particular solution. (1) Next time, i solved the same case (without a single change) by initializing it from 'All zones'. This time also, i solved it for five time steps and each time step was converged. When i compared the solution from this case to the solution of previous case (1), i was astonished to see that these two solutions were totally different. I don't know which one to trust. I was under the impression that, even if u initilize from different domain, you should get fixed solution at the end of certain time step, if u achieve convergence at each time step. Can anyone explain me why this is happening? Thanks, Nikhil |
