Iteration Problem
 
1 Attachment(s)
Hi!

I have worked about catalytic reactions with CHEMKİN 24 step reactions. When i get initialize and start calculation i get this screen and i couldn't get any iteration. Anyone can help?

can anyone help about this?

It is only one point. It should be still calculating and after 2 iterations it will draw a graph.

Does Fluent hang after the first iteration or what are you trying to say?

after first iteration it see like picture and i wait so many times 1h, 2h and more but it won't get 2. iteration.

Did you change any solution parameter, such as maximum number of (inner) iterations? Does your computer hang, or is the CPU still running at 100%?

Hi,

Try your model on a very small dummy mesh and see if it runs as it should (without necessarily converging, just to see if it runs).

Dummy mesh how can i do? I can't understand :( can you define pls.

Sorry if I wasn't clear. I meant on a coarser mesh, or smaller geometry, or a combination of both, so that your computer doesn't freeze when it starts solving.
