Any feedback is welcome. Abstract.
pde2path 2.4 is a continuation/bifurcation
package for systems of PDEs over bounded d-dimensional
domains, d=1,2,3, including features such as
nonlinear boundary conditions, cylinder and
torus geometries (i.e., periodic boundary conditions), and a
general interface for adding auxiliary equations like mass
conservation or phase equations for continuation of traveling waves.
The original version 1.0 was for elliptic systems in 2D and based on the Matlab
pdetoolbox, which since v2.3 has been more or less replaced by the free
OOPDE. Recent additions (v2.4) include the handling of multiple steady
bifurcation points, Branch point continuation and Hopf point continuation
via extended systems, continuation of relative equilibria (e.g., traveling waves and rotating waves), and branch switching from periodic orbits
(Hopf pitchfork/transcritical bifurcation, and period doubling).
