Good afternoon everyone. I have a question in relation to solution initialization. When i go to solve, initialize, initialize in fluent, there is a reference frame option given, either relative to cell zone or absolute, and they both give very different results. What is the difference between them, and how do i determine which is the more appropriate for a given problem.
Re: Solution initialization
The uniqueness of a result depends on your boundary conditions, your physical data and probably your numerical settings. Usually initialization doesn't effect your results, as in, regardless of how you initialize your case, you should get the same results once you achieve convergence. It will effect the time it takes to achieve convergence though.
Probably you can explain more about your simulation case, and more on what you mean by giving very different results.
