A Pseudo Dynamic Method for Solving Nonlinear Algebraic Equations
A widely convergent method for solving nonlinear algebraic equations is described which combines the algorithmic features of Gear-type automated stiff ODE solvers and Davidenko-type Parameter Stepping methods. The method consists of variable-order variable-time step transient analysis, with prediction and truncation error control, in which the Newton iteration on the final time step gives the desired solution. The method is shown to be efficient in model problems taken from the applications area of semiconductor integrated circuits.
