Advection 1D Example 1

1D advection with a constant velocity. The equation is qt + uqx = 0.

The velocity is specified in, along with the width parameter of the Gaussian pressure pulse used for the initial condition.

Boundary conditions are periodic.

After running this code and creating plots via "make .plots", you should be able to view the plots in _plots/_PlotIndex.html.

The true solution is computed in If you change the initial conditions, this should be changed accordingly. (Except that if beta is modified and the code rerun, then then reloading setplot should read in the latest value of beta used.)

Adapted from ‘$CLAW/classic/examples/advection_1d_example1’ to use adaptive mesh refinement.
