Hi all
Mr.feizaghaee
I try to examin low number of meshing, and i found that the parameters such as "mass flow" in it, isnt conestant in several section unlike the simulation with great number of meshing.However i know this number of meshing isnt correct,too.

how did you decrease your mesh. you shouldn't decrease the mesh normal to the main flow.

Dear
you just can control mesh in all directions in independent form(refine one side of grid) with structured mesh, i think. so this problem

can't be solved in Workbench; as it just do unstructured meshing in cfx mesh(again as I think!!)

Hi
I could use ssg model in cfx12! but now it does not converge even after 2000 iteration!!!
What do I do? Please help me.

how many mesh do you use? what's your time scale?

I assume you are running V12.1? Then look at the release notes for V12.1 and see what is relevant to you which changed. They tweak the numerics all the time and maybe one of those tweaks is causing the problem. In the release notes they usually describe a way of reverting back to the original behaviour so this should allow you to pinpoint the problem.

thanks ghorrocks, yes I'm running V12.1. your scope is I peruse the conditions with changing the parameters basis on these notes? At all is it necessary to recieve the convergence? and how mutch it does effective in my results?

Well, if you don't try then you won't know if one of the changes in V12.1 is causing the problem! How much do you want to know? If you don't care then don't bother doing it.
