Explore the Clawpack Gallery to find a 2D advection example. Navigate to its rendered HTML page, identify the specific numerical method(s) and limiter(s) used, and determine the initial conditions for the density (q[0]) and the velocity components (q[1] and q[2]) in the simulation.
Navigate to the Clawpack Gallery (or use the search bar if not already there). Search for '2D advection' or browse the gallery to find a 2D advection example. Click on the link to the rendered HTML page for the 2D advection example. Scroll through the 'Source' section of the page to identify the numerical method(s) and limiter(s) used. Continue scrolling to find the initial conditions for density (q[0]) and velocity components (q[1] and q[2]).
Successfully navigate to the '2-dimensional advection' rendered HTML page. State the specific numerical method(s) used in the example. State the specific limiter(s) used in the example. State the initial conditions for the density (q[0]). State the initial conditions for the x-velocity (q[1]). State the initial conditions for the y-velocity (q[2]).
