Yes, just the first. But I am still not familiar with the point of numerical simulations, I have bought a book on it, and read a few papers, but they all don't explain the core intention of numerical sims:
If it is not to solve the PDE, what is the point of inserting a trial-function unless it has some analytical validity (thus analytical method is required anyway), and therefore what is the real gain of getting a plot of a numerical representation of the change of the solution during a given time frame? If there was an example as simple as "one box of apples of 24 apples times two makes 48 apples" to illustrate what we can get out of a numerical sim, that would be excellent. But also that is difficult to find, even on google. Thanks!
