Hello everyone,
I ran a 3D model with ASPECT2.3, but it always stopped at "Solving mesh velocity system … 11 iterations " after 4000 years.
There are my input file and output file.
origin.zip (10.8 KB)
Let me know if anyone has any ideas. Thank you !!!
Thanks,
Xiao
Add:It has been stuck at this step for a long time without any output.
@Xiao As a general rule, if you are trying to debug a problem, try running in DEBUG mode – your program is running in RELEASE mode, but you get many more error checks in DEBUG mode that might help you with figuring out what is wrong.
The second recommendation is to see whether you can reproduce the issue with fewer processes. You are using 1280 MPI processes, which is a very large number given that you have less than one million degrees of freedom. There is guidance in the manual on this issue, and my suggestion would be to use <10 processes for a problem of this size.
Best
