How to perform a discretization of the PDE?
To perform the integration in t, we discretize the PDE by approximating ∂u/∂t with the forward difference scheme, and ∂u/∂x with the central difference scheme (this combination is but one of many possible choices), ∂u ∂t i , j ≈ ui, j 1−ui, j t

And you get to choose between 10 different Graduate paths. You will begin your ascent at either our Danish headquarters in Copenhagen or with our Swiss af“liate in Zürich.
How is a solution to a discretized partial differential equation obtained?
A solution to a discretized partial differential equation, obtained with the finite element method. In applied mathematics, discretization is the process of transferring continuous functions, models, variables, and equations into discrete counterparts.
Discretization is also related to discrete mathematics, and is an important component of granular computing. In this context, discretization may also refer to modification of variable or category granularity, as when multiple discrete variables are aggregated or multiple discrete categories fused.
Is there always some amount of discretization error?
Whenever continuous data is discretized, there is always some amount of discretization error. The goal is to reduce the amount to a level considered negligible for the modeling purposes at hand.
