How do you solve a PDE numerically?
In solving PDEs numerically, the following are essential to consider: •physical laws governing the differential equations (physical understand- ing), •stability/accuracy analysis of numerical methods (mathematical under- standing), •issues/dif?culties in realistic applications, and •implementation techniques (ef?ciency of human efforts).
What is the history of numerical solution of differential equations?
While the history of numerical solution of ordinary di?erential equa- tions is ?rmly rooted in 18th and 19th cen- tury mathematics, the mathematical foundations of the ?eld of numerical solution of PDEs are much more recent: they were ?rst formulated in the landmark paper Uber die partiellen Dif-¨ ferenzengleichungen der mathematischen Physik
How are differential equations computed?
While the differential equations are de?ned on continuous variables, their nu- merical solutions must be computed on a ?nite number of discrete points. The derivatives should be approximated appropriately to simulate the physical phenomena accurately and ef?ciently. Such approximations require various mathematical and computational tools.
What is elliptic partial differential equation?
