Figure 1From: Artificial viscosity in comoving curvilinear coordinates: towards a differential geometrically consistent implicit advection scheme Example of a non-conformal non-steady 2D grid with oblateness governed by three choices of parameters ( a 1 , a 2 , a 3 ) as defined in equation ( 1 ). (a) corresponds to ( a 1 , a 2 , a 3 ):(1,0,0), (b): (0.8,0,0), (c): (0.8,0,0.5) and (c): (0.8,0.2,0.5).Back to article page
