NDK and its examples are under constant development, more information and content will be added to this example soon!
This example demonstrates how a simulation can be executed and stored in one computer and the results can be loaded and rendered later in the same computer or another one.
Execute the following code in a computer with ndk installed
import neurotechdevkit as ndk
scenario = ndk.built_in.Scenario0()
scenario.make_grid()
scenario.compile_problem()
result = scenario.simulate_steady_state()
result.save_to_disk("scenario-0-results.tar.gz")
Out:
Estimated time to complete simulation: 44 seconds. Memory required is 8.09906664298232 GB (available 73.624408064 GB). These values are approximated.

A result artifact has been saved to scenario-0-results.tar.gz.
The output file from the previous step could be copied to another computer with ndk installed or stored for future use. The results can be loaded running the following code:
import neurotechdevkit as ndk # noqa: E402
result2 = ndk.load_result_from_disk("scenario-0-results.tar.gz")
assert isinstance(result2, ndk.results.SteadyStateResult2D)
result2.render_steady_state_amplitudes(show_material_outlines=False)
Out:
Total running time of the script: ( 0 minutes 12.848 seconds)
