Fourth-order time stepping for stiff PDEs
A modification of the ETDRK4 (Exponential Time Differencing fourth-order Runge-Kutta) method for solving stiff nonlinear PDEs is presented that solves the problem of numerical instability in the scheme as proposed by Cox and Matthews and generalizes the method to non-diagonal operators. A comparison...
