Linear Convection Problem at different values of n

Objective: On increasing the value of n,initially the curve gets better with its increase from n= 20 to n=80. But on n=160 we can see that disturbing waves starts falling on the result which is completely ruining it so its not stable at n=160. while at n=80 its the most stable and least stable is at n=20. %Inputs for the linear convection…
