>> plotSolution(s, domain, component)

s:

Instance of class Sim1D.

domain:

Name of domain from which the component should be retrieved.

component:

Name of the component to be plotted

function plotSolution(s, domain, component)
    n = s.stackIndex(domain);
    d = s.domains{n};
    z = d.gridPoints;
    x = s.getSolution(domain, component);
    plot(z, x);
    xlabel('z (m)');
    ylabel(component);
end
