```julia
load_checkpoint_jld2(file_path)

Load the state of the simulation from a .jld2 file.

Arguments

  • file_path: The path to the .jld2 file.

Returns

  • stokes: The loaded state of the stokes variable.

  • thermal: The loaded state of the thermal variable.

  • time: The loaded simulation time.

  • timestep: The loaded time step.
