Hi,
I'm conducting a transient heat transfer simulation, with a DEFINE_GRID_MOTION UDF controlling dynamic mesh motion. I've conducted this simulation a number of times without issue, but recently it started hanging 63% of the way through and not finishing. When it hangs, the console displays the following text:
Code:
Flow time = 54540s, time step = 909
531 more time steps
Updating solution at time level N...
done.
Updating mesh at time level N...
>> Dividing domain into 1 partition using Metis.
Time = 0 seconds.
Done.
>> 1 Stored Partitions:
----------------------------------------------------------------------

Cell count 6506 6506 6506
Mean cell count deviation 0.0% 0.0%
Partition boundary cell count 0 0 0
Partition boundary cell count ratio 0.0% 0.0% 0.0%
Face count 9932 9932 9932
Mean face count deviation 0.0% 0.0%

Mean solid cell deviation 0.0% 0.0%
Partition neighbor count 0 0
----------------------------------------------------------------------
Partition Method Metis
Stored Partition Count 1
Done.
..
Done.
I'm trying to solve this pretty urgently for an assignment, so would anyone have an idea why this would be happening all of a sudden? The strange thing is I have even gone back and attempted to re-run the simulation with my old settings, but am still running into the same issue, making me think the source might be something outside Fluent. Any ideas?
Thanks!
