Discontinuous patches in surface plot


Sometimes surface plots (Plot3D) in Mathematica can show discontinuous patches.

Use exclusions none (Make sure the exclusions are unphysical)


Plot3D[Re[Bands[J1val, J2val, kxval, kyval]], {kxval, kxv – delta,
kxv + delta}, {kyval, kyv – delta, kyv + delta}, Exclusions -> None]
