Simulation always stops after 1000 seconds

Zerzura · January 13, 2016, 04:29

Good day everybody,

Every time my transient simulation passes the 1000 seconds it stops. There is no divergence, it just finishes the last iteration and sends the message:

" Flow time = 1012.8s, time step = 29
971 more time steps

>
adapt/ file/ report/
define/ mesh/ solve/
display/ parallel/ surface/
exit plot/ views/

> /file/write-case-data

> exit"

It knows there are still 971 time steps to go, why does it stop iterating?

I already checked my Max-time-on-flow and it is on "unlimited". I work on the cluster.

Your help is much appreciated!

Kind regards

Thank you very much for you answer!

I already solved the problem with help from a friend.
The answer is, by putting an adaptive-time-stepping method and use a UDF for time-steps, the setting for you ending-time is set to 1000 seconds by default.

You have to change this as well, so not only the max-time-on-flow.

Kind regards
