figure : curve of velocity convergence

Hello dear
please in solution of navier stokes equation i need figure explain convergence curve of velocity with number of step-time or Reynolds number or rho please how i can get this figure with the solution of navier-stokes with axisymmetric coordinates
...... with my greeting

Making custom convergence curves is not quite supported with existing functionality. You could technically write a custom Matlab function that takes the velocity and time step as input, plots the convergence, and just returns "one" as output (which effectively does "nothing"). The format for user defined functions is described here:
