Relativistic Orszag-Tang vortex: in-plane quantities. Relativistic Orszag-Tang vortex. Left column: small differences can be observed in this snapshot of the Lorentz factor at \(t=5.0\). Some features that appear when using CT are flattened when using GLM, possibly due to a greater diffusivity of the latter. Middle column: final snapshot of \(B^{i}B_{i}\). Good agreement between the two methods can be seen, except at some extreme points. Right column: violation of \(\nabla\cdot\boldsymbol{B} = 0 \).
