How to use the restarting procedure
Have a look at the following video to see how easy it is to use the restarting procedure in Xcompact3d.
There are only 3 parameters to deal with:
istart: first iteration of the simulation
ilast: last iteration of the simulation
irestart: switch from starting the simulation from the initial condition defined in the BC files (0) or from starting the simulation from a restart/checkpointing file (1).
Another parameter of interest is
icheckpoint which is the number of time step between writing a restart/checkpointing file.
Please note that Xcompact3d will only keep on the disk the latest restart/checkpointing file (called
checkpoint). Details about the restart/checkpointing files can be found in the
*.info files. If you want to save different restart/checkpointing files (intermediate ones for instance), you will have to do it manually.
The code for the restart/checkpointing files can be found in
