[CIG-SHORT] Pylith stuck in the final step "Formulation finalize."

[hkj at mail.ustc.edu.cn]

Dear Sir,
I'm now running a .exo model with 55000 nodes. In the pylith simulation I used total time = 50 yr with dt = 0.01yr(since I need viscosity to be small, 0.01yr is the largest time step as pylith suggested).Thus the output file is about 80GB.


The simulation and iteration run correctly, but it has about 20% probability to stuck at the final step after it shows "Formulation finalize".


I waited for about 10 hours(even longer than the whole simulation time), but it still stuck at the final step. The last few lines of output is showed below




``` [OUTPUT]

```


Is it the normal case since the output file is too large?
