% You may want to experiment with the neighbor number and the AGGRESSIVE_SLOPE_LIMITERS or
%  SLOPE_LIMITER_TOLERANCE and KERNEL_FUNCTION (try =5 or 7 instead of 3) settings, 
%  to see how the numerical diffusivity is affected on this problem (you have significant 
%  room to trade stability/noise versus diffusivity, and the problem in any code is, at this
%  relatively low resolution, strongly influenced by the slope-limiter)
