hye. i am still newbie and still need a lot to learn and not know much on how the system will converge. i only know, it converge when the graph fall below 10e-4. can take a look at my graph below to see if it converge or not. and for heat transfer, does it needs to fall below 10e-4 also? many thanks

thanks for that reply. ive read it, but still i can't tell if wether my simulation already converge or error...

Let me quote the relevant section:

The first thing to consider is whether your simulation is sufficiently converged even though your specified criteria has not been met. To check whether your simulation is sufficiently converged, output the parameters important to your simulation to monitor points and display them in the solver manager. Appropriate parameters could be lift, drag, pressure loss, flow rate - what ever is an important parameter to your simulation. If these parameters are not changing to an accuracy tolerance suitable for your simulation then your simulation is almost certainly OK as it is and no further work needs be done.

u mean by this? so thats mean my simulation had converge rite?
