JustRelax.DataIO.checkpoint_nameMethod
checkpointing_jld2(dst, stokes, thermal, time, timestep, igg)

Save necessary data in dst as a jld2 file to restart the model from the state at time. If run in parallel, the file will be named after the corresponidng rank e.g. checkpoint0000.jld2 and thus can be loaded by the processor while restarting the simulation. If you want to restart your simulation from the checkpoint you can use load() and specify the MPI rank by providing a dollar sign and the rank number.

Example

```julia
checkpointing_jld2(
    "path/to/dst",
    stokes,
    thermal,
    t,
    igg,
)

```
