How to load and plot history points

Parameters for simulation with history points

To generate history points, one needs to specify in a Snek5000 solver,

params.output.history_points.write_interval: int = ...
params.output.history_points.coords: list[tuple[float, float, float] | tuple[float, float]] = ...

For example, see the parameters used in the tutorial for snek5000-cbox.

This should be coupled along with a hpts() call in userchk() subroutine in the Nek5000 user file. For more information, see documentation for params.output.history_points in snek5000.output.base.Output.

Loading and plotting

Use load* and plot* methods in class snek5000.output.history_points.HistoryPoints. A working example of this can be found in a tutorial where we process results from a snek5000-cbox simulation.
