Thanks for the post @swetarkad23. The restart has some glitches and we are working on them currently. @etsandall , would you be able to take a look and possibly apply a fix to @swetarkad23 Can you please provide a complete example so we can reproduce your issue? https://solidsgroup.github.io/alamo/docs/Questions.html |

@etsandall I faced this earlier. Now, when I restart a case, I name the output directory different name. So alamo reads the restart file from existing output directory from previous run and starts writing the new restart results in newly named another output directory. Let's say if it ends at 1s and I restart the case from 1s again, then alamo writes the new output directory. But right at the beginning of the first time step it fails after showing "STEP xxx starts ..." with a 'Segfault' error.

@swetarkad23 Okay, thanks for confirming that. Can you please provide the info requested by @bsrunnels per https://solidsgroup.github.io/alamo/docs/Questions.html? This will help me reproduce and hopefully isolate the error. |

Hi @bsrunnels ! Yes I am working on this and updating ScimitarX branches in sync with latest alamo development branch. |

Uh oh!

The alamo documentation suggests the restart is done using the following command:
<executable_name> input.file restart=/address/of/the/output/directory/upto/final/written/data
This is not working with an error being showed:
amrex::Error::0::Couldn't open file: //00008cell/Header !!!
I checked the code and the Restart function in Integrator.cpp which suggested a 'restart_cell' input in the input file, I did that as well, by providing the address of the final written data in the input file. But, it fails at the first iteration only.
So, if anyone can pour some idea about how exactly the restart of a simulation is done in present state of the alamo code, that will be really helpful.
thank you.
