Dear Ian,
I used parameter file in ~/Cactus/par. It seems this parameter is only used for the first run instead of restarting. And yes, I am using simfactory. I follow your steps to edit the parameter file in <simulation>/SIMFACTORY/par and successfully recover my simulation.
Thank you.
Best regards,
Chia-Hui

Dear who it may concern,I have tried the binary neutron star simulation (http://einsteintoolkit.org/gallery/bns/index.html), and want to finish the simulation by parts .That is , I would like to recover the simulation from checkpoints. However I fail to continue my simulation. There are two cases that I met:
- I have the cctk_final_time=2500 and the simulation terminate at time=2500 but the merge has not yet occur which means I need more time ,perhaps time=8000. So I want to continue my simulation from time=2500. But after I changed to cctk_final_time=8000 in parameter file , the simulation still stops at time=2500, which means it stops just after it begins. How can I finish the complete simulation?
- I have test the same simulation as above but with wall_time=10 min. I have checkpoint_every=150 ,and checkpoint_on_terminate= "yes" in the parameter file. However after it finishes with the final iteration=250, the checkpoint file is not produced. Only the initial one checkpoint.chkpt.it_0.file_0.h5 exists. How can I produce a checkpoint which enable me to restart simulation?
