<span style="font-size: 11pt;">I am trying to simulate a laserslab problem with an initial sinusoidal perturbation embedded (figure attached). As shown in the figure, I initialize the perturbation wavelength to be 125 um on a target width of 500 um (along x).
I don't understand why the perturbation is non-periodic? When I measure the wavelength manually in VisIt, it turns out to be ~ 130 um. </span></div>
