Enabling the Iterative Solver

The iterative solver provides an alternative to the direct solver. When you select the Enable Iterative Solver option, Maxwell invokes the iterative solver. Maxwell automatically switches to the direct solver if the iterative solver fails in convergence.

For more detail, see the technical notes for Iterative Matrix Solver.

To enable the iterative solver:

1. On the Solution Setup dialog box Solver tab, check the Enable Iterative Solve check box.

   This enables the Relative Residual input field.

2. Enter a value for the Relative Residual. The residual measures the convergence of the iterative solver. The default value is 1e-6 for the magnetostatic and electrostatic solvers and 1e-4 for the eddy current solver.
