Simulation always stops after 1000 seconds
 
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
