I am using the new PDE workflow in MATLAB R2016a (but have been experiencing the same errors in the legacy workflow on R2015b, hence the upgrade to 2016a). I am solving a parabolic PDE on a 3D geometry. The f coefficient in the PDE is required to vary as a function of time. I had easily solved a second order PDE in MATLAB using finite difference method but I am not able solve the above first order PDE. PDE Toolbox does not have an interface to specify periodic BCs. However, it is easy to modify the system equations to enforce periodicity if your geometry is simple and your mesh has identical number of nodes on the periodic boundary pair.

  • Tower databaseFeb 27, 2012 · Method of Lines, Part I: Basic Concepts. The method of lines (MOL) is a general procedure for the solution of time dependent partial differential equations (PDEs). First we discuss the basic concepts, then in Part II, we follow on with an example implementation. Though MATLAB is primarily a numerics package, it can certainly solve straightforward differential equations symbolically.1 Suppose, for example, that we want to solve the first order differential equation y′(x) = xy. (1.1) We can use MATLAB’s built-in dsolve(). The input and output for solving this problem in MATLAB is given below.
