Robert's flow test

Note: all runs were conducted without explicit artificial resistivity.

Robert's flow I with cubic box

Magnetic field configuration for 32^3 run (B_x/B_{rms},B_y/B_{rms},B_z/B_{rms}) in xy plane at z=0.05 at \eta = 0.1811.

Growth rate vs resistivity for 64^3 runs

Growth rate vs resistivity for 64^3 runs (ideal MHD limit, resistivity in log scale)

Critical magnetic Reynolds number convergence with resolution

Volume and time averaged divergence error vs resistivity

Divergence cleaning efficiency and impact on growth rates.

Brown - run with cleaning and large initial divergence, Green - run with cleaning without initial divergence, Yellow - run without cleaning with initial divergence.

Ideal MHD limit pattern destruction (resolution limit)
