📝 WalkthroughWalkthroughThe Harris 2D current sheet simulation test was refactored for improved modularity, diagnostics, and plotting. The main test script was enhanced with updated physics initialization, diagnostics, and plotting routines, and restructured into a test class. The previous load-balanced test script was removed, consolidating testing and plotting functionality into a single, more maintainable file. Changes

3-3: Remove unused import
osis imported but never used.-import os
23-23: Prefernp.linspacefor evenly–spaced diagnostics
np.arange(0, final_time + time_step, final_time / 5)relies on floating-point step size and can miss the intended end point on some hardware.-timestamps = np.arange(0, final_time + time_step, final_time / 5) +timestamps = np.linspace(0, final_time, 6) # 0,10,…,50
152-154: Sanitise filenames generated from floatsPlain
f"{time}"will produce “0.0”, “10.0”… but also long representations like “0.0500000000001”.-return f"{plot_dir}/harris_{qty}_t{time}.png" +return f"{plot_dir}/harris_{qty}_t{time:.3f}.png"
157-184: Load diagnostics only once per time stamp
Run(diag_dir)is inexpensive, but the plotting loop re-parses HDF5 files for each derived quantity. Cache the object per timestamp to cut I/O by ~5×.E.g.
for time in timestamps: ds = run(time) # hypothetical lazy loader ds.divB(...); ds.ranks(...)
187-195: Modernisesuper()and record simulator handlePython 3 allows the shorter
super().__init__()syntax and storing the simulator avoids double-reset logic later.- def __init__(self, *args, **kwargs): - super(HarrisTest, self).__init__(*args, **kwargs) + def __init__(self, *args, **kwargs): + super().__init__(*args, **kwargs) ...
200-205: Use stored simulator to simplify teardown- Simulator(config()).run().reset() + self.simulator = Simulator(config()).run() + self.simulator.reset()Avoids the “if … is not None” guard in
tearDown().

147-147: Load-balancer tolerance: deliberate?
tol=0.05triggers rebalancing for 5 % imbalance; this can introduce noisy performance for small runs. Confirm that such an aggressive threshold is intended.

we have no artifacts for harris
and it only runs with one level, which is not such a great test
sample bz from this after 10 timesteps at t = .05
