Hello Experts,

I'm a newbie for Flowtherm software.

3 questions here:

1) I face a difficulty to judge which condition (steady state or transient state) setting i should set for my project.
Project condition: one main PCB is place inside plastic enclosure with a small opening hole which allow air room to flow in with speed 0.65m/s.

2)initially, I'm using steady state setting to solve this project yet i failed to obtain converged result with couple tried. Oscillating profile obtained during steady state setting. So, i decided to have a try on transient analysis setting.
With Transient analysis, i obtain a message window write on " Solver stopped: all monitor points are stable" after done the simulation. Does this mean of "converged"? Picture is attached.
Transient setting: increasing power with 1.1 index in 3600s

3) continue question 2, if it is not converge, does it because of the temperature residual is not stable (still hanging and not yet reach zero) as shown in pic attached? How am i going to solve this problem?


Thank you.
