Here [rho] and E are scalar quantities representing the mass density and total internal energy, respectively, v = [(u, v, [omega]).sup.T] is the velocity field with Euclidean norm [v.sup.2]: = [[parallel]v[parallel].sup.2], and B = [([B.sub.1], [B.sub.2], [B.sub.3]).sup.T] and [B.sup.2]: = [[parallel]B[parallel].sup.2] represent the magnetic field and its norm, respectively.

Flow data continue to be displayed in three ways: as plots of a flow scalar property as it varies along a cross section of the flow field; as contour plots of either scalar quantities or the magnitudes of vector quantities throughout the flow field; and as what may be called "arrow" vector plots, which represent vector properties, usually velocities, at regular intervals across a region of the flow field.
