PDE Problem Setup Basics

Set up problems using pdetool or command line functions

The first step in setting up a PDE problem is to create a PDE model container for the equation or system that you are going to solve. The parameters of your partial differential equation or system, such as number of equations, geometry, equation coefficients, boundary and initial conditions, mesh, and so on, will be stored as properties of the PDE model.

When using the PDE app, the first step is to open the app by typing the pdetool command.
