Numerical methods for coupled stiff PDEs
I'm dealing with a set of nonlinear coupled PDEs that have the form:
\begin{align}
\frac {\partial y_1}{\partial t} &= y_2y_3 - y_1 \tag{1}\\
\frac {\partial y_2}{\partial t} &= y_1y_3 - y_2 \tag{2}\ …

Implementing odespy for system of PDEs
After trying to use RK4 to solve the below system of equations, it appears the output had large and fast oscillations even with an adaptive time step I incorporated using the Cash-Karp method. I am no …
